Preacherman, you may just be confused...
Isn't a Mauser too much gun for a Siamese, whatever the caliber?
Perhaps it's iffy for a Russian Blue, and probably a bit light for a Maine Coone, but a Siamese should be just fine.
Siamese Mausers properly converted to .45-70 are considered one of the few actions strong enough to withstand a steady diet of Category III .45-70 ammo, the others being the Ruger #1 and #3, and the Browning Hi-Wall.
Properly converted is the operative word here. Category III .45-70 ammo is a big leap in ballistic oomph from the Category I ammo intended for use in the old Trapdoor Springfield.
WildAK was alluding to the fact that converted military rifles seldom garner much in the used rifle market, unless there's some provenance attached, ie. vintage Sedgely Springfields, A-Square Hannibals built on U.S. 1917 Enfield actions, etc. Likewise, if it's a conversion done by P.O. Ackley, it's no longer just a collection of military parts.
I've got a Siamese Mauser action, barrel, and Bishop stock that are being assembled into a .45-70 repeater. The original rimmed 8mm Siamese round was close enough in rim dimensions to make the conversion to .45-70 relatively straightforward, with minor modifications to the bolt face and magazine rails, plus the usual bolt welding/forging, etc. Again, properly done, it makes a hard-hitting repeater that can handle the stoutest of .45-70 loads. I plan on using mine for dangerous game some day in the future.
Hard nailing down a price on that one. Like JShirley said, it depends on how nice a conversion it is. Fancy wood, Belgian or deep rust bluing, fit, finish, etc.
