Trust me, any collector would want jump at the chance to buy some armor. I bet you'd get at least enough to pay to get to Oslo and back, probably more.
Actually, I bet I could get to Oslo - or another nearby city, and just hop on a train and meet you. It's really easy to travel around Europe that way, and even if my bank accounts are being monitored, it wouldn't look suspicious to be traveling overseas. I do it all the time. So don't bother to tell me not to. ;)
If not, then definitely send me a postcard as a backup plan. I love those.
