Heterogeneity Of Red Nine Broomhandle Grips

How many grooves are found on original grips of the Mauser 9mm C96 WW1 contract? Also known as the red nine broomhandle. Recent discussion on this forum prompted a review of some available grips.

Figure 1. Here are the typical red nine grips from a late 9mm C96 serial number 139358, one of the last to be made in this WW1 contract using serial numbers from 1 to 140,000. Typical 23grooves on each side (23/23).

Figure 2. Red nine grips from an early 9mm C96 serial number 175, with 31 groves on both grips (31/31). The grove pattern on this grip is similar to that found on the 7.63 wartime commercial C96 that was concomitantly in production by Mauser. Note the shallow grooves on top and bottom that may be lost during finishing or refinishing.
During WW1 Mauser made two C96 models for the Military. The 7.63 wartime commercial starting around serial number 280,000 in November 1915, and then early in 1916 they received an additional contract for 150,000 9mm C96, starting at serial number 1. Subsequently it was found that two similar C96s with dissimilar ammo was a problem in the field, so on 12/14/1917 Mauser was directed to burn a nine into both grips the 9mm C96 and fill the number with red paint. Those 9mmC96 already produced and issued by December1917 were to be marked in the field.
Below is a list of original red nine matching grips with number of grooves and type of nine(factory or field applied).Data added from WW1contract 9mmC96s supplied by forum members .The obvious field applied nines are noted.

This minuscule examination suggests a change during production in 9mmC96 grips from a fine to a course pattern. The fine grip pattern (30-34) prevails in the red nine series below serial 50,000 whereas the course pattern grip ( 22-24 groves) appears characteristic in the red nine series above serial 50,000.

For the purpose of generating discussion and data, I will speculate that the change from a fine (30-34) to a course groove pattern was prompted by and perhaps coincided with orders for the Mauser factory in December1917 to apply red nines to the grips of 9mmC96 during production. The nine is deeply etched by burning/carving and there may be less chipping-out with a wider ridge of wood as found on the course 22-24 groove grip.

The big question is- What was the serial number of 9mm C96 in production in December 1917 when Mauser started applying red nines to grips of C96 during production.
Can the nice red nines, that appear to be from the factory, be used to identify the post 12/1917 production? Apparently not, because most grips of the early production 9mmC96 were marked with what appears to be a nice factory red nine (e.g. look at red nine #175 in figure 2). Were they returned to factory for their red nines? No known directive supports this idea. Or were new red nine grips sent out from factory? Doubtful, as these grips are routinely numbered in factory style and would have also required individual fitting.
On the other hand, some of the 9mmC96 that were issued before 12/1917 with unmarked grips were never marked with a nine on the grip, or were marked in the field with a small nine or an obvious non-factory nine.

Figure 3. Grips from red nine serial number 27706, an early 9mmC96 presumably made before 12/1917. The crude red nines on these grips (33/34 grooves) were obviously applied in the field. Other variations include smaller 9s and various colored-uncolored nines. Also some of the early imperial accepted 9mmC96 grips were never altered in the field (non red nine).
Therefore the serial numbers of early 9mmC96 that are not marked with a nine or marked with a field applied nine may provide an estimate number of guns produced before December 1917.
Information from forum members about original matching grips may provide enough data to make some meaningful conclusions from this very preliminary survey. Data should include serial (or range), imperial accepted?, 1920 rework?, number of grooves and presence of apparent factory nine or field nine or no nine marking.
Questions about the grips of the red nine contract to be answered:
1. What is the highest serial number in this series that does not have an apparent factory marked red nine grip (i.e. grips with no nine, or obvious field applied small/aberrant nine) and are these found only with the fine (30-34) grip pattern?
2. What is the earliest serial number with course (22-24) grip pattern? Do these grips all have the red nine that appears to be the nice factory nine?
3. What is the latest serial number with fine grip pattern?
4. Perhaps other subtle grip variations/transitions will become apparent with more data.

The transition from fine to course grip pattern may be gradual and erratic considering the well known thriftiness of Mauser, and their usual practice of using up the old parts after a new modification appeared. On the other hand, if there were “left over” fine pattern grips, they could have been used in the ongoing production of the 7.63 Wartime commercial C96.

Thank You Bill,
Your red nine has been entered. It would appear from the preliminary data that 24 groves were the norm at the time 106044 was made. I assume that 106044 has what appears to be factory made red nine? Is it correct that 106044 was not imperial accepted and without "NS" mark or new safety?

The grips on #106044 appear to be factory made (old, poorly fitted & lanyard ring indentations).
#106044 not imperial accepted and without 'NS' marked hammer.
I hope this helps with your efforts on the survey.

Many thanks Paolo,
I have entered your data in the list, and designated the nines on 11470 and 43593 grips as field applied nines. Your 43593 is one of the higher field nines that I have seen. So far the great grip heterogeneity of early production seems to stabilize in later production to a 24 groove pattern with a final 23 groove pattern. Interesting to see if more data is consistent with this grouping.
It is possible that many of the 1920 Police reworks used red nines that had been in storage. Storage of non-issued 9mm C96 is suggested by the presence of groups of 1920 modified red nines within a close serial range without an imperial acceptance mark. For instance, MacMahon (automag p217,vol27Dec,1994) observed 3 non imperial proofed 1920 reworks in the 119k range(119455,119866,119924) and I have seen 3 more in that 119k range.

I'm sorry I didn't get back to you sooner about the Red Nine mark. As far as I can tell it appears to be factory made. I matched it up with Paolo's photos and it matches up good with the 3rd photo down. Hope this answers your question.
