The highest serial number for a new Model No. 3 I have is in the 351xx range. The highest known number is 35796, so I think you would be safe to assume that RCMP will accept any of the New Models as antique. Some years ago, I met Richard Nahas at the Vegas show and he put me in touch with Roy Jinks. We had discussed the possibility that all No. 3 frames were made before the end of 1898, not 1899. Roy agreed, stating he only picked the 1899 date because that's the legal cut-off for US antiques...
As far as modifications go, knock yourself out! As long as the frame stays the same (and is antique), and you don't change the caliber to one of the no-go's you're good. You can cut off the barrel, add a shoulder stock, scope, laser sights...
The factory letters provide date of shipment, not date of manufacture.
