There is a modified 59 on GB that I talked myself out of earlier today before the first auction ended.
The gun smithing appears to be first rate but I'm unconvinced that it was a Devel or one of the other 2 or 3 well know purveyors of modified 39's and 59's.
Someone with more knowledge may draw a different conclusion. I'd be most interested in some expert opinion. I've no intention of placing a bid on the pistol at this point.
Here's the expired auction info -
