I'd say my falcon FN19 single shot in full L/H model.
Bought brand new from Henry Cranks in Pudsey but I was skint and it had to go. Only 6 month after buying it and the dive bottle for over £650 and i let it go for £350. Gutted wasn't the word
HW80 'Bavaria' - standard stock in beech laminate - 0.25 calibre.
Still gutted to this day. Even thought of getting a laminate stock made for another.
BSA Meteor .22 - the mans calibre
Every rifle sold has been to aid/allow purchase of the next, as I have ended up with the two that I class as "ultimate airguns" in a .20 MFR & FAC .25 Rapid I can't call any sales "mistakes".
Left hand Falcon Light Hunter with a lovely stock.

FWB65. Still the pistol I shot my personal best with when I used to shoot target pistol seriously. I thought the spanking new Hammerli PCP target pistol would be better; it probably was just not better for me....
Frog
RWS Excalibre, carbine. Simple to maintain and super accurate. To this day I don't know why I sold it.
