I bought the materials to make all 19 of them.
Even an expensive PR Mark 4 originally cost me £85 and about 120 hrs labour 9 years ago.
Havent actually bought many though do own a few, ashamedly i admit to owning an AA.
The only gun i paid full whack for was the Anchutz 9003 then needed sorting and the only air rifle i would pay good money for, one of three converted in the UK/World. Top it off with a Premier Ret VX3 20-50 one of the very last **** Thomas modded. At Welhams prices looking at £6k mine about £3.8k.
Do own a Walther, its been in bits for 4 years and used to do the loads of inletting.
