The factory short stroked Tommy was great, but the long strokes were a bit too lazy. I also really like the smaller Webley - the Xocet I think it was - still near full power and light and easy enough to shoot.
And defo the RB2s were the best of BSA - Superstar first then Airsporter. Goldstar didn't really do it for me, but it wasn't bad. Any of the Mercs with a breach bolt (not pin) were fine, but somewhat nondescript; I'd much rather have an equivalent webley.
In my own collection, all I have from the above is the RB2 airsporter - sold my superstar ages ago. The carbine in .177 is the one to have, and is on my "buy when a cheap one comes up..." list. As is the Omega / Exocet...
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
