Was at a Airgun show today and picked up a BSA Standard, looks to be in the 1920s given serial number S18133 ? (Looked in Vintage Gallery quickly). Shooting old style 22 pellets at 520 fps? Just happy it shoots! Lol. Pictured it next to the Browning AirStar for the old and the new. Is that date about right?
