the people who evaluate antique guns have a refence guide/book they use. they also need the gun 'in hand' to note the condition for themselves. based on their findings, they can attach a value to an antique piece..........in a lesser way, you, too, can evalute an antique pistol by securing an antique gun book and compare your pistol to the condition they list. buy a copy of "bluebook of gun values" thru Yahoo or your book store.
Value of ANY gun will be based on condition- and in the case of an antique, originality. DO NOT clean up an antique- what you call dirt, collectors call patina. There is no way to give a value without a hands-on assessment by a person that knows antique British pistols. It may be $50, or $500.
What are the markings on the pistol?
You should ask an antique seller or antique expert to determine the value of body jewelry.

The authenticity of an antique is the reason the item has value. Antiques have the price that they do because they are old. If an item is simply a reproduction, its value will be less than that of the real antique.
The item is an antique of great value.
i know they were made in the 70's
Stand off distance
It depends on the quality of the antique. If it is of high quality and in demand, refinishing it might diminish it's value. I would check with your local antique shop.
The value of any "Antique" is always a very subjective opinion. research what a similar item has sold for and you will have your answer.
When a classic car becomes a antique, it's value increases due to the popularity.
WWII Japan made one or two military type (style) revolvers, and the rest were semi-automatic Nambu pistols during the war, mostly in 8mm caliber. Single shot pistols are either antique muzzle loaders or special cartridge firing "target" pistols. Hardly no military during WWII had need of single shot pistols.
