Greenville Works Mass. Rifle 1864

[joe n]

I was helping a good friend today go through a number of old rifles he will part with one day. This one in particular caught my eye. It is I beieve marked Greenville Works Mass. Apart from a period repair to the wrist, it seems to be in nice original configuration. I have never seen one like this before. Can anyone tell me a bit about this rifle, including what value would be fair to place on it? And when it was manufactured? Thanks in advance for educating me
P.S...a few pics of the other oldies in the pile.

Looks like a second contract Warner carbine made by the Green Rifle Works.

Looks a lot like a knock off of the Whitney Phoenix rifle only slightly different. I notice that it appears to have British proof marks on the barrel, so it must have found its way there at least for a while
