No, both the 2 bores in the 3rd vid were made by my old apprentice (now one his own and doing well)
His name is Colin Stolzer. Colin is without a doubt the worlds most experienced man in making 2 bores. I made one the one above. Colin has made several more and it's likely that he had made (my guess) 90% of all the sporting 2 bores on earth. I am sure both were made for the same customer that ordered Gun #1 from me. He was a regular on this site a few years ago. BigDog was his screen name.

They were both made after I made the 1st one, in the pictures. Ken "BigDog" wanted a breach loading double. I suggested Colin because I have the capability of only making the muzzleloaders and all my parts that can't be made on my lathe are hand made with hammers, files and a hack saw, whereas Colin has a milling machine.

The 4th vid started with a picture of my hand holding the above 2 bore at the muzzle, and again several seconds into the video, but all other pics were of things that had nothing to do with me.
Here are pics of the gun when it was in the process of me making it.
