Frank,
Righto, I agree. The SS link and the BW nomenclature are strictly fairy tales. The value/rarity of the BW is simply because it is another collectible variation. I think there is some inflation because of the SS fantasy. Cleary, unknowledgable buyers frame their bids around this fantasy, and if you want to own a BW variation, then this sort of inflation is an unavoidable problem.
I've got a page on my website which trys to offer some clarity on this. Here's a link,

By the way, in my discussions with other collectors, it seems that there is a consensus as to who is responsible for inventing the "Black Widow" designation for this variation, but, I'm not certain who came up with the SS tag.
Geo/Keoki,
Let me see if I understand your point (assuming that the grips you used were authentic).
You replaced the walnut grips with BW grips on a byf 42 and sold it at a higher price.
If your remark, "So much for the rarity of black widows" suggests that BW's are not rarer and more expensive,
then one of us needs to go back on our medication.
Have I misunderstood you?
Pancho
PS. Add-on grips...no, no, no.
