I'm certainly no expert, but it sounds like someone rebarreled stateside long after leaving Indonesia. The vickers Lugers are generally rough, so a great find all in all.
How much did you pay for it, if you don't mind my asking?
I try to follow up on the vickers as much as possible. The last one on GB was $2750, Simpson has had one for a while at $4000, and there was one on Julia I've been meaning to find out about
