Desert Rat Angus

Hello there! I got into airsoft as a teenager and haven't played or used any of this kit in just under ten years. It has been kept dry and away from sunlight and is all exactly in the condition that I put it away in, which I'm quite happy about. Looking to get some opinions on how much this is all worth second-hand (and third-hand), it seems like this sort of stuff is a little harder to find outside of Soldier of Fortune than when I bought it. If you know anything about any of these individual items at all, please let me know! All information is welcome. List of all pictured: 1937 British Battle Dress Jacket, small, with Oxf. & Bucks Airborne Glider Regiment Patches. British Gas Mask & filter, dated 1944. (Worn only once, before I found out the filters contain asbestos 😅) British Gas Mask Bag, stamped 'H&S 1/44'. 1941/42/44 combo British Battle Webbing with two pouches, water bottle and backpack with backpack straps. Backpack is a reproduction, pouches and bottle are I think actual surplus but don't take my word for it. Also an extra webbing shoulder strap, not pictured. Webbing is not blanco'd. Belt is labelled 'X-Large' but is extremely adjustable and also fits me perfectly at a small. Map case 1942 or 1944, but no clue as to the authenticity since the item it isn't dated. Two pairs of bef gaiters, one pair sized '3' and one pair sized '5'. Make of that what you will. Both in good condition, size 5s are more worn. MK2 Tommy helmet, with webbing and hessian camo strips. Very good condition. Not sure on the size, but it's certainly too small for my big head. Again unsure on if surplus or repro. MK2 Para helmet with canvas chinstrap, very used condition, reproduction. One of the pouches, the Mk2 Para helmet and the map case are all marked by previous owners as pictured. Again all information is welcome! I'm leaving the country quite soon so I'm also looking to get rid of this stuff for the right buyer. Cheers!
