I emailed Mr. Smith to ask his opinion. As none exist, size is pure speculation but 3/4 to 1" seems reasonable. Also one stock could have different size spots throughout. Technique, again speculation, aqua fortis dabbed on in spots. Heated an tada! Spots. I'm seeing this for my next build. I think it would be an interesting piece. Odd though, documented to the period, but complete speculation as to process and appearance.
So I'd like you opinions. The stock wood I'd be using is maple. I'd use ferric nitrate like I used on my short jaeger. The color was great. But since I'd only be putting a dab here and a dab there, how would I finish the stock? Some kind of oiI finish. Obviously I'd want the spots to be in contrast to the rest of the stock to stand out. Would a treatment like oil on walnut or beech work? Thanks for everyone's help.
