Please help - where I can buy 2nd Hand Roman Armour/Kit

[Aurelius Romulus]

Thank you to both of you for your replies - greatly appreciated. Apologies for delay in replying, though i have been away with work for a couple of days. I am a 1st Century AD Roman re-enactor and have a fair bit of the kit & always check authenticity with the societies I am a member of, though buying new all the time can be very expensive - especially as both of my daughters have really enjoyed taking part in shows/events & are now civilian re-enactors and kit for all 3 of us gets very pricey and trying to save costs by adding to our supplies with some 2nd hand kit seems to make sense.
You both mention either marketplace & traders on this site, though I am not sure where to look as I am barnd new to this site & will be using it a lot more in the future. Please could you point me in the right direction for finding these?
Many Thanks for your assistance
