Old firearm, any ideas on age etc?

Martini cadet was the first thing that popped into my head, but I don't reckon it would be a single shot with the lever action would it?

It is definitely not Martini Henry or Cadet. On those rifles coking lever was separate from the triger guard and it did not have a hammer.

hexagon barrel should help identify it

Very cool, I'm a gun nut myself but I cant quiet identify this, I keep thinking Uberti for some reason.

If nobody minds ill copy the pics and try to get it identified.

That's a Winchester 1866.

That's a Winchester 1866.

Looks like one to me

 

[jaksdad]

I cant tell from the OPs pics if the receiver is brass or steel, the majority of 1866 were brass receivered but I believe there is a steel receiver variant which is a bit rarer.

Winchester. Had a very long production run. Very nice find. The ower maybe buried nearby -)

I also think this a Winchester, but which model I'm uncertain, short of model numbers, caliber marking on the rifle, a little more easily obtained info on this rifle could help determine which it is, e.g., measure the length of the barrel, measure the bore size as close as possible to help determine the caliber.
