Rolf,
I've followed your work progress since you started here, and I really like the pistols you've made, and bet they're a blast to shoot!
Far be it for me and my abilities to critique your work, however, if I were comparing your pistol to the work of the top makers here, I'd suggest that you could work on improving your metal to wood inletting.
As is, you do a nice job, however to bump up to that top workmanship level, some of the gaps are a bit too noticeable.
Particularly, I'm referring to the pictures that show the metal to wood fit along the top side of the side plate, the tail of the entry ramrod pipe, and the upper side of the forward ramrod pipe.
One other thing, and it might just be the picture, but the trigger guard looks a bit thickly constructed. I know you made it from scratch and overall you did a fine job, but I think a little thinning of the metal around the bow area, and at the weld area for the back end tang would have made the guard look a bit lighter and more fluid looking, in keeping with the overall look of the pistol.
Little things, true. And just my opinion. But I suspect you're planning on being the best you can be!
John
