Thanks to everyone who's replied to my post. John Allen of Game Fair actually handled the transfer when I bought the gun. Consulting him on who he's used for repair work was on the list and maybe should have been done before posting here. I'll certainly give him a call.

I've emailed both Geoffroy Gournet and Kirk Merrington, based largely on discussion in this and similar forums. Mr. Gournet has been responsive but pretty terse. I get the impression he is very busy. I haven't heard from Mr. Merrington. It's only been 5 days since I emailed him at the start of a weekend leading to a holiday week, so I'll probably give it some time.

The gun has the cross-bolt safety that protrudes from either the left or right side of the receiver. Pushed right-to-left, the protruding portion shows a red band, indicating the gun is ready to fire. Pushed left-to-right, it is supposed to be in "safe" mode. On a whim, I decided to give the safety a trial and was dismayed to see the bolt migrate from safe to live position in response to pressure on the front trigger, followed by a released firing pin. Not good!

Ted, are you saying that a simple rotation of the cross bolt might solve the problem? That would certainly worth a cautious try.

Thanks again to all!

Bill
