Jim,
Going to start my Kibler rifle soon and want to do a matchbox like your design on it. Is there any way you can share the dimensions and possibly a photo of the outline that we novices can us to try and make one ourselves? Also, what was the thickness of the steel that you all used? i believe I have some from one of the big box stores that is 22 gauge and some that is 16 gauge. Seems also to be discussion if to be HC, these boxes had 2 or 3 screws. I do not have the book you are referring to but I assume you are referencing points from that book. Thanks and look forward to your posts.
