Doverham,
I ordered a custom triggerplate (round action) gun through Krieghoff & I found Krieghoff N.A. extremely easy to work with on a custom order. I was able to specify non standard 29" bbls., no gold other than a gold "S" indicating safe position, a checkering pattern with a mullered border similar to the pattern Westley Richard uses, blued triggers at no extra charge. They also provided me with pictures of available stock blanks to chose from. The gun is engraved Krieghoff Essencia in small script on the bottom of the action & I was told "it has to be marked Krieghoff somewhere". Of course I was able to specify stock dimensions, chokes, trigger pull weights etc.
I looked at the Heirloom Arms website but did not talk to them & I know nothing of them. Their pricing appears to be out of date & I don't think includes engraving. Also their round action guns pictured have the lump piercing the bottom of the action. Scotty's gun & the Krieghoff sourced guns don't.
I'm sure you can save some $ if you can go direct. I chose to go through Krieghoff as I've found their service department to be excellent & they were very good to work with on the custom order.
If you should choose to work with Krieghoff I would recommend talking to Nick Ranzau @ Jaqua's Fine Guns & Jacque Baughman @ Krieghoff N.A. in Ottsville P.A.
