I was researching a Winchester Model 95 in .303 British when I found this gem for sale:
BSA Co Lee-Speed No. 2 Officer's Carbine - wasn't on my bucket list, or even on the radar ...
Not perfect, but still a heart-stopper. It wasn't listed as sold, but unavailable - quantity zero (0). I couldn't determine its status. When I was finally able to get hold of the owner, he told me it had been sold.
Missed it by that much ....
