The other one, unless it is clearly the same case, might be a .43 Spanish??

It's a different cartridge. Unfortunately ruptured so I can't measure case length etc. rim is dimensionally similar to the 45-70 at 0.638 in. Case body ahead of rim is 0.526 in. Also picked up what I thought was another 45-70, but when I cleaned of the dirt was marked Winchester 45-60. Cool. As far as I know that would have come from a M1876 Centenial.
Measures close enough to 43 Spanish, and it makes sense for the location (post Spanish American War). 43 Spanish: Rim Dia 0.635 and Base Dia 0.516
My guess was based on general appearance of head - which is not like any .45-70 with which I am familiar.
