Springs for a Model 8 n .25 Remington

[Badenpowelloldsport]

I had a new barrel made for my old circa-1912 Remington Model 8 in .25 Remington, but still need the appropriate recoil and buffer springs for it. Parts houses sometimes hint that springs for the .25s are different from the springs for the .30, .32 and .35 Remingtons. Does anyone know if this is true? Does anyone know of a smith well versed in the Model 8 who could offer counsel?

P.S. I inadvertently first posted this in the Post-1898 Handgun Forum. Rookie mistake.
