According to Flayderman's, a No. 430 was Identical but with fancy grained checkered stock & forend.
A No. 435 was identical but with extra fancy checkered stock & forend; matted top of receiver with engraved designs edging border of receiver on both sides and on lever.
A no. 440 was identical but with fancy checkered stock and full scenes and panels on receiver (with bear designs, ect,) engraved forend tip and lever.
Calibers were 25, 30-30, 32, and 35 centerfire. I believe Remington Rimless.
I have only seen pictures, but they looked like a nice little rifle with a 22" barrel.
