Does anyone know the approximate value of this pistol?  It's a Merwin & Hulbert/Hopkins & Allen Pocket Army (Caliber Winchester 1873).  7-inch barrel, cylinder does not rotate when hammer is cocked. Any assistance would be greatly appreciated. 

I appreciate the info!

Very likely did serve in the US military during the WW2 days and then was either just handed over to a friendly foreign country or shipped to a friendly country post war as “military assistance”. Greece, Germany, Denmark, the Dutch and Italy all were supplied with Garands post war. The numbering on this bayonet looks WAY better than any numbering I’ve seen on a Greek return FWIW.  I would be inclined to think it came from another source country.

Thank you for your answer.

. History repeats itself sixty years later.    An article from today's newspaper featuring a stock photo of surplus store inert grenade.  And a memory of doing the same thing sixty years ago ( aged 10 ) at junior school with a 1940 Mills grenade my mothers younger sister took home with her from the munitions factory she worked at.            Norman D. Landing, Forum Normandy Correspondent, May 17 2O25.    ….

Thanks for your answers. Is it produced in the US in 1942 and is it possible to say if it “served” in the US army during ww2 and after ww2 were supplied to Greece or was it supplied to Greece during ww2?

The photo is not of John B. Crandall, but of his brother Richard B. Crandall (Sixth Vermont Infantry) - brothers - both ancestors of mine.  Richard B. Crandall (in the photo) was killed by a sharpshooter in the battle of Cold Harbor.  I'm writing extensively about him.  I have included photos of John B. Crandall.  Should you ever be interested in offloading the medals, I would be interested, although I don't know the costs of these sorts of things.  

Definitely not Vietnamese related at all in my opinion. Construction doesn’t resemble any Asian made patches. Not really sure if this is even a military piece 

Thanks everyone!      

Thank you for your reply, Honestly the value doesn't matter to me so much as any potential history of the piece. Is it known if stuff like this was done during the war, interwar period, WW2? Or are knives like this pretty much exclusively assemblies from far later? Regards, Andrew
