I think RI is nuts. They thought an english double rifle of mine was worth $1800 and they want some ridiculous percentage of the selling price. I sold on my own for over $6k.
Anyway, custom guns are tough to sell as far as I'm concerned. A Borchardt a bit more so for several reasons. But I think patience is the biggest factor, and I doubt you will really recover your money in this market. You should get close, but not a lot more.
just my opinion.

PS. I love to see pictures of custom Borchardts (but I'm definitely not in the market - you see, I have one already).
