magazine prototype P-08 mfg. 1901
 

are saying?

Not really. Or better 'really not' :)

Looks like some home made thing from the 1970s.

germany ? made in

and now this reviewer

frommer stop

The next iteration was the Model 1906. The first few 1906 pistols retained the early 10-round blind magazine, but the design was soon revised to use a more modern but smaller capacity 8-round removable magazine (which would serve as the model for the Luger P08 magazine). The Model 1906 was chambered for a proprietary cartridge, the 7.65 Frommer. This model is also very rare, with only about 800 made. They were tested by the Austrian military, but lost out to the Roth-Steyr (which would be made in the same factory where Frommer worked).

Home?
if I believe that if it was made at home
but Frommer Rodolf house in 1900

I sincerely doubt that he would have used aluminum for the base in 1900 ....

It looks like whoever made it used as zig-zag spring as well, again something that was not common in those days.

Hugo, Is this magazine a .22 caliber?

The round in place is a bottleneck round. It looks like the typical .30 Luger, or as Hugo has pointed out, a 7.65 Frommer.

Hugo,

I'm not making much sense of this. If the Frommer 's 8-round magazine was introduced in 1906, how could it have been the prototype for Parabellum, which used the 8-round mag in 1900?

Also, I'm wondering when an aluminum bottom was first used on any pistol--Borchardt and Luger were wood back then, which material persisted for this purpose for 20-30 years for the Luger. (I have no idea when Al was used by other mfgrs.)

The angular compression spring Gerben points out--when did any pistol first use the radial compression spring in its mag?

I don't think the round that sits in the mag in the pic. is .22, judging its appearance/proportions--but it might explain a 10-round capacity for the initial blind mag system.

The follower button , aluminum bottom and the mag body all look like the cheap Mexican copies I have seen.

Early magazine 1900 production not perfection
they later evolved.
In previous test some time trail
magazine this could have been a test
made in a workshop production as a project
i send photos to detail
sorry for my english

Vlim:
wood was common in 1900
for military testing in 1900 aluminum was used
experts could confirm

pictures magazine rare mark

That is some pretty bad welding. Again this points towards some locally or home made contraption, probably just to create a functional magazine for a pistol that was lacking one.

Nothing experimental about it, other than an experiment in making an ugly magazine :)

When copies are made in many places, they also mimic markings like the "Germany" on this mag's base.

yes, they can confirm that aluminum was not used on luger magazines until the mid 1920's

no matter how hard you want to believe this is a special magazine, its not period correct

I would have to agree. This is a locally made, (Mexico) magazine that some gunsmith produced to fill a need, since products like this are extremely hard to obtain in Mexico.
