Your Luger is the most commonly encountered model of all Lugers. Give or take, it was made in the 1925/1926 time frame and known to collectors as an "alphabet" commercial Luger due to the letter "p" (not n) suffix. The "GERMANY" stamp indicates that it was made for export to the US.
While yours appears to be matching from what I can see and has the correct wood base magazine, it has been modified; the stock lug has been ground off. This likely dates to a misunderstanding about the 1934 National Firearms Act (NFA) that forbid attaching a stock to a Luger and similar guns. I once had one like yours with only part of the stock lug ground down so a stock wouldn't fit. People thought that if the gun could accept a stock that it was illegal. It wasn't and isn't.
Because they are seen more often than other models and most are in .30 caliber, they hold little interest for collectors. The good news is that they are very well made and are excellent shooters. If you shoot yours, I strongly suggest that you buy a Mec-Gar mag and keep the original mag for display only.
