Bought a box lot of stuff recently. Within the lot were a bunch of things like NOS Colt New Service parts, S&W revolver parts, some Colt Pocket Auto parts and some other stuff I was familiar with.

What I was NOT familiar with were these two barrels that appear to be for Asta autoloaders. One is marked 9MM & .38 with a S/N and the other is unmarked. Both are covered in old hard cosmoline: https://www.flickr.com/photos/...04/shares/43tq847Wv6

Any thoughts on identification?

Thanks.

I have a few.

The long one should be marked Largo. I see it's marked 9m/m & 38
Which is the 38ACP.

The bottom is the Astra 600 9mm.

Thanks for the ID on the bottom barrel. Any idea what model(s) the top one might fit?

Astra 400.

Thanks!
