Well, the bottles wont be able to be sold on here for safety reasons, and the markers are both WDP Angels (from different years) and wont be worth much either (no matter how fancy they look) maybe £50 (black one) maybe £80 (silver one), but thats a guess as these are old guns and you probably dont know if they even work or not?
The other sundries, maybe a £10 for the lot. Loaders look broken and or pretty old. Barrels are older, heavier types. Not much call for them really.
