Slightly late to the party but if you're getting into MTB'ing again "Zinn and the art of mountain bike maintenance" is a fantastic source of info for overhauling and reconditioning bikes. Buying it has probably saved me a few 100's worth of maintenance done by shops.
Wolf shutting down is a shame. IIRC they were the cheapest place in the UK when I pre-ordered the NGRS MP5SD (yup never thought I'd type that sentence).
I also never really had an issue with most of the staff tho that may be that on my visits I went in with a definite shopping list and an occasional 'ooooo whats that'.
I have had plod turn up after I ordered a streamlight tlr1 and a holster from the states. They turned up and asked a few questions, it was all rather civil and happened about 4 weeks after I'd recieved the items.
That said...... if it is half way decent watch the market for £300+ 'drop in'hpa systems collapse.
Edit 2..... like the dude above me said about 9 hours ago

Genuine ex police surefires for £75. If they are legit thats probably the bestest deal ever.
Dammit. That Robben guy had the exact item Ive been putting out wanted ads for for almost a year........
I was fishing to see if he was too good to be true.
As above I've seen more consistantly questionable play from skinny yoots in jeggings and hpa'd capa's in gopping colourways.
Also Ive seen more speedsofters turn up to organised and specified milsim days and expect to be allowed to use their hpa murderbox rigs than milsim players turn up to speedsoft sites and insist everyone uses non-winding mags for example.
Unfortunately the bell-ends in both styles ruin it for everyone else who is capable of playing by the rules.
