Hello mate and welcome to the Forum. Would love to hear some of your tales about working on EP. VIII.
We don't have many rules on the Forum, but pretty much all are around selling items. The most important one here is price: if you want a price for an item ask for it. If you want a best off/auction type thing, best you head on to eBay that specializes in that form of selling.
There a number of crew collectors here who would love your jacket and pay good money, but please post a price and pictures.
