That came out real nice. Don is the king when it comes to snakeskins. I have never had the pleasure but all the times I have seen these his work stands out. That is a nice shine on that one for sure. Whatever method you are using works well. Thanks for showing.
Something that you can't tell from the picture is that it is possible to line-up the patterns. The skins are cast perfectly plumb. I want to make sure that I credit Don for perfect casts.
Just line any patterned blank, it is not always so easy to find the thread and barrel starting point so that the pattern matches when fully threaded (capped). I tried a half-dozen times and got "close" (only good in game of horse shoes and hand grenades) .
