An 'Artillery' Nambu and Lahti

I always try to use a 'spare' barrel/barrel extension for my projects. This is because if I make a mistake, it's not the end of that handgun.

A word or two on Nambu 'interchangeability of parts'...There is none...

I used eBay/GB parts for this project. Here's my take on that...

It would seem from my observations that the Nambu is pretty much part-matched, and any interchange of parts will require some searching and trial-and-error matching or hand fitting.

Parts that I've noticed that require particular attention are -

- Barrel extension and locking block. Locking block must be able to fully retract (a straight line) or it won't even allow the barrel extension to be assembled.

- Bolt and cocking knob. The knob, when fully screwed on, must line up with the firing pin extension.

It would seem that the best solution is to get all the relevant parts from the same handgun.
