The number on the buttstock does not match the receiver, but DOES match the fore-end! #247489 (1920-1921).
The butt plate is a type 2 per D.P. Murray as is the barrel address marking.
It looks like a 1899 H, but of course with the wood not matching the receiver, who knows what was on it originally.
Its has definitely been re-blued, and no trace of case hardening on the lever.
Stock is straight, as is the lever.
I'm assuming the re-blueing was done at the same time as the scope mounting holes were d&t'd.
