FWIW, the Model 1936 was only made 1936 & 37, before changing the model designation to "Model 36", up to 1947 - when it was discontinued in favor of the enclosed round bolt Model 336.
ALL Model 1936's were color case-hardened, & had thinner Perch-belly forends, fluted buttstock comb & a HR buttplate.
No Model 1936's had letter-prefixed SN's.
I don't believe the OP's Model 1936 to be refinished - if it is, only an artist of Doug Turnbull's skill could do so, w/o messing with the perfect barrel & receiver stampings; AND the wood/metal fit, especially abound the tangs are perfectly even, an indication the wood hasn't been sanded since it left the factory.
The two D/T'd & plugged holes atop the rear half of the receiver are factory prep for a Hepburn rear peeep sight.
Some Marlin's of that time were issued with sling swivel / eyes - the Deluxe's.
They looked a lot like the Winchester Deluxe/Supergrade units (here's a factory Marlin):
If I had that rifle to sell, I certainly wouldn't sell it locally - I'd list it in an online gun auction with more/better pics and a full description, to realize the maximum return for it.
