■Miroku Harper's Ferry Flintlock Style Antique Gun
Model Gun 2-Piece Replica
Rare Item, Showa Retro

■(Larger one)
From the 70s? (Showa 40s-50s)
I believe it's a Miroku, but please judge from the images.
If you can tell me where to look for markings, I will check.
It functions. The hammer can be pulled back and the trigger pulled.
The flintlock mechanism also operates.
It is heavy and has a realistic construction.
I researched it, but could not find any information beyond the name above.
There are several markings, so please judge from those. (US marking, crown mark, serial number?)

(Smaller one)
It looks like it might have an action, but neither the push nor pull mechanisms work. It might be a decorative model only.
It is lighter compared to the larger one.
It might be best to consider this as a bonus item.

■This was part of the cherished collection of my uncle (over 80 years old) who used to work for Japanese National Railways.
As I am not an expert, this information is based solely on my online research. If there are any inaccuracies, please let me know.
I would like to pass this on to someone who will cherish it.
