Can anyone ID this 1800s perscussion rifle?

This is from my dad's collection, who was a Civil War collector. It's around .38cal and I'm not sure if it's rifled, but there is no rifling at the bore. I need to find a better light to get down in there. It's around 4ft long and has a really heavy barrel. I have been told it could be a G.P. Foster percussion rifle and it does look very similar. The gun is worn so you can see some faint decoration, but there aren't any markings that I can see. The only other place could be on the inside of strap the stock attaches to, which I haven't checked out. Any ideas? I'm just using his photos, I haven't taken new ones yet, so sorry about the limited views.

I have a very similar rifle , but smaller , lightweight  , my rifle is built like an Ed Wesson rifle that is pictured in  the "Muzzloading Caplock Rifle " book by I  believe Ned Roberts.

Wesson was my first impression upon seeing the 'action'.(from Ned's wonderful book)
Appears to have been bored smooth. Would have been a rifle and likely a bullet firing rifle of .35 cal. maybe?

Here's a few Wesson rifles for comparison. Note the "back action" lock:

It could also be George Pratt Foster. The iron frame wasn't exclusive to a single maker.

Looks like an Allen and Thurber, or influenced by them, to me. At least the front part.  The front of the receiver and metal fore end are typical.  Ethan Allen designs had a long metal receiver though, like shown here:
