Title: DUO Dates
Post by: czechollector on June 11, 2023, 10:04:58 PM

Has anyone ever seen a '46 or '47 dated DUO?

I haven't seen those years in a DUO.

My 1st DUO is 1949 with S/N 179xxx.

I just bought a 2nd DUO today which is stamped '41' with a S/N 17xxx.
I'm pretty sure it is an early one with the low S/N and it also says "F. Dusek Opocno".
My 1949 one says "CZ".

About this new one...after getting it apart, it has the following problems:

• Broken firing pin
• Missing firing pin guide rod
• Wrong magazine (again!)
• A much longer/stiffer recoil spring than my other DUO

My 1949 DUO came with 2 mags.  Using snap caps, only one of the 2 feeds/cycles correctly.
It's a good idea to test them to make sure they work.

Sadly Numrich and others that I've looked for in the last hour are out-of-stock or already sold.

My earliest DUO is 22XXX.

Hope you're able to find the parts you need.

I forgot to mention that there is a Lion with a crown over an 'N' (smokeless powder proof) next to the '41'.
To the left of the line is "6840".

Same Lion proof mark also on the barrel.

I think I've found a firing pin online.

I'll take photos and post measurements between the my two to help figure out what parts (if any) are the correct ones.
