Beautiful old gun, Tony.
I kind of like the recessed sear idea. In theory, it should allow more wood to remain in the head and the lockplate really doesent need much material at that point anyway (lighter too ;>). Look at that wonderful, long mainspring with evenly-filed arms and note the little "chamfer" on the sear spring. Not needed, but certainly a proud touch.
It would be nice if the safety sear was over-hanging and somehow used as the main for better mechanical advantage. I've always thought Holland Dominions (Blanch-made?) should be that way too. Some A&D guns I've seen with similar main sear geometry have little slivers of metal laying under the bent where the sear has "shaved" the tumbler; lots of pressure is needed to hold the sear that close to the tumbler pivot and if parts arent exactly the same hardness...... An over-hanging sear requires much less pressure and gives nice trigger pulls too.
I'm not exactly sure how the Blanch saftey sear works, would it be possible to see the back of the tumbler? I'm missing the "notch" the saftey sear engages. Is it on the tumbler?
