Not sure about the value but:
The helmet is the latest version of the liner. The old one had a couple of bright leather bags. This one is not sold commercially.
The stridsväst is in very good condition and fairly complete. The camo pouch is non issue and the canteen pouch is an extra add on. The only pouch you are missing is the duell/fast pouch (Duellficka).
The vests are hard to come by and airsofters in Sweden pay a range of 1.000-3.000 SEK for them ($120-350).
