Well, part of the problem is that you haven't given much info that would help pinpoint it's age or model. The serial numbers won't help that much since it was quite common for contract purchases to specify unique serial number sequences. Unfortunately, that means there are likely duplicate serial numbers out there and many undocumented series as well. Afterall, this is one of the most common guns ever made.
The markings you list simply show that it's a P-35. Not a Browning import so I wouldn't look on their site. Browning Arms was a fairly recent player with the HiPower anyway. IIRC Browning Arms started selling the HiPower in the mid fifties, or about twenty years after it was introduced.
Here are a few things, beyond a picture, that would help. What shape hammer? What do the grips look like? Try looking at pictures of the different models of P-35s made over the years and see which looks closest to what you have. Pay attention to internal features. Is there a firing pin block? Is the blue bright, shiny and deep or is it a semi mat finish? Is it original blue or has it been re-blued? Are the grips wood, rubber, plastic? Does it have an ambi safety?
