I doubt if it was a "kit".
It was mfg. in Japan for Ultra-Hi. It is a copy of the British Tower pistol; On the lock plate it should have a "crown" over letters G R impressed between the hammer and frizzen; the letters S A R behind the hammer. The brass butt insured that the wood would't split when it was used as a club; after fireing your one and only shot.
This is just an educated guess; but it may have been made by Miroku; a top Japanese gunmaker. (I have a caplock .45 pistol; Ultra-HI; Miroku: Japan; and I've fired it. The workmanship is top notch.)
The presense of "proof" marks indicates your pistol is intended to be fully functional; it looks unfired.
As posted; it is worth at least $75 but not more than $200.
Collector value is in the eye of the beholder.
I own the exact gun you described in your reply post. If my gun has a Crown over GR and SAR behind the hammer does this mean my gun is authentic vs. a replica? The gun is in very good condition and appears to be in full working order.
Any idea on its value if all parts are authentic? Can you tell me anything more about its history?
