Hi,
It's not the magazine tube.......

I wondered if anyone might be able to help me get one of these repeaters up & running. I'm after a retaining block for the magazine, it's the one on the trigger end of the cylinder. I'm pretty sure the blocks were the same for the Paratrooper, Sniper & the various 'matic versions. Hoping there might be one surviving somewhere in a spares box or on a rusty, beyond worth saving example that someone might be happy to break.
If you have anything that might be suitable I'd be pleased to hear from you,
