16" barrel Weimar commercial 1920
 

Looking for help figuring this Luger out. Crown N Commercial proof, Weimar 1920 date, matching serial numbers including the magazine but it has a 16 inch commercial crown U marked barrel with matching serial number. Any guesses?Attachment 83108

The commercial guns in the 1920’s came in all sorts of configurations. These longer barreled carbine assemblies included. The front stock doesn’t seem to be DWM factory vintage though.

The magazine seems to be Weimar/3rd Reich period for a military gun.

In the period following WW1, Lugers were made with many different barrel lengths including 16 inches but the fore-stock looks to be made from an old rifle stock. The workmanship appears to be somewhat questionable and I suspect it didn't come from Germany that way.

Judging from the way the fore stock is attached to the barrel, this is one of the new aftermarket barrels that Numrich is still trying to sell. TH

It does resemble the Numrich barrel and stock but who would bother to stamp the barrel?

Here's a 16" Numrich barrel to compare. I have never tried to fire it.
Here's a close up of the flange. The profile is different than a regular barrel.
I don't have a better image at the moment.

Years ago on 'Relics Of The Reich' was selling a 1923 luger with a longer barrel than an artillery. I think I also saw it pictured in Harry Jones book! Ill take a look, no stock! Something like this!

Found It At 'Lugers At Random'. Page 158, 1920 Long Barrel Commercial~

Barrels that are too heavy mess with how the action cycles. The early .30 Luger Carbines, of course , had a helper spring in the fore stock to help return the gun to battery, and the barrel and extension moved independently of the furniture.

This one makes me wonder whether the shooter needs to pump the fore stock like a shotgun...y'know, to help get that big pipe back into battery. :biggulp:

I was thinking that if you had a good grip on the fore-end/barrel and just touched the trigger, the frame would 'anti-recoil' forward... :D

After WW1 many surplus military 9mm PO8s and new 7.65mm 20 commerical lugers were imported into the USA by Stoeger on the east coast or Pacific Arms on the west. Both firms offered in their catalogs barrel instalation options of either caliber and barrel lengths up to 24'. Most of these longer barrels came with the LPO8 type tangent rear sights. TH

"It does resemble the Numrich barrel and stock but who would bother to stamp the barrel?"

And "who" would use the wrong marking? The C/U stamp was not in use in the 1920s either.

But- "who" also had a lot of number/letter stamps and made a kind of numbers matching
"Franken-luger". ;)

I have had two 16 inch shooters that have that same older (60's/70's) fore end. Neither could I get them to work correctly.
Only 16 inch 9mm I could get to work was the one that Eugene made for me, it shot just fine.

Ed, I agree that getting a 16' barrelled luger to function reliability is difficult. Due to the weight of this longer barrel, the recoil spring will have to be lighter. This tend to reduce the toggle return, unless all mating surfaces of the frame & receiver have the minimum amount of friction. TH

You'll have to give us more clues than that... :D
