Don't get me started. Some of them weren't really anything special, but I do regret selling them.
A VGC BSA Superstar with rotary type breech, boxed with original target holder.
A beut of a Lazaglided HW77
My Webley Raider 10 (s)
A Venom 95k
A TX200 HC
All in the last 2 years. Bought and sold many more, but those are the ones I really wished I'd kept. Still early in the year though..
