Great advice on the uniforms, ive book marked a few pages as you mentioned the Belgium and Greek stuff and it does look very similiar, i'll take a more indepth look tomorrow when i get up. I'll also have a look at the webbing on ebay too as i only looked for five mins at it on there in the past. Blancoing is not a problem, i was considering doing it to the canvas heat shroud on the suppresor anyway but i was also thinking of just doing a paracord wrap around it as the canvas slightly blocks the front sight and a paracord wrap would be more streamlined although less authentic.
On an unrelated note modern military surplus uniforms were cheap as hell at the militaria fair, i picked up two MTP and Two DPM British surplus shirts for 50p each, two MTP trousers for £5 each and a DPM and MTP windproof jacket for £10 each. It's just the older stuff that is over the top. I was contemplating a T-Stock for the STEN but i can imagine just that piece of steel on its own would of been £50+. Maybe next time.
