I've still got an HW80 in the loft, an old German long barrel import, not one of the ones made by the Hull Cartridge Company in the UK. Bought it off an old man about 25 years ago from the Trade It paper (does anyone remember that?).
Added a 3x9x40 and a silencer, so ironsights removed, the standard spring and guide were replaced with custom venom parts, also tried doing a custom staining job on the standard stock which didn't turn out as well as I'd planned. It looks OK but you can tell it's DIY.
I was looking at getting another standard stock, refitting the ironsights and using it for a bit of target practice before selling it to someone who will actually use it regularly rather than leaving it languishing in a loft.
It's big and heavy but incredibly accurate for a springer once you get used to it. What are the chances of someone being interested in this old behemoth?
