Exactly my point Homer.......... they were actually making that woodwork on site and while it differs slightly in configuration, they didn't have to tool up afresh. And you've forgotted one VERY important point too................ There is paperwork to support/qualify your rifle too - or is there?
What exactly is that rifle Homer? A shortie SMLE with an aperture sight on the charger bridge? Someone did a (inconclusive.....) paper on these short rifles a year/18 months or so ago
