Welcome to the Board.

Ted Schefelbein will likely chime in shortly. He's a former DARNE agent here in the States, and active on this board.. The current is Geoffroy Gournet, whom you might be able to contact by googling him, or at http://www.gournetusa.com.

I've had Kirk Merrington do work on my own Darne and he did it well. Go ahead and google Kirk and then enquire to see if he wants to handle your needs.

By the way, what grade Darne is it?

Regards
