Adam, I got the same response as you. I've replied to this e-mail with attached price lists inquiring about their "US partner" so one here in the USA may be able to inspect and handle some of their offerings---I'm awaiting their response.
It should be pointed out that the prices we posted are guns with Grade #3 wood, they also have listed Grades 4 and 5. Grade 5 carries an upcharge of $940 over Grade 3. The pics of the sidelocks you posted appear to my eyes to be upgraded wood---but of course, I could be wrong.
I was wondering what grade the stocks in the photos would be considered. Like you said, GRADE 3 is standard, but it doesn't mention if the wood shown is upgraded or not. If I do end up ordering a gun, I'll most like upgrade the wood to their best grade.
I am seriously considering ordering both a boxlock and sidelock. The BIGGEST thing stopping me is the unknown factor of quality. Plus, I'd like to see close up photos of the engraving.
Adam
