They are from an old saddle shop that some friends of mine own. They were extra tools that they didn't use that were stored away for more than 30 years.
Another problem that Bob has had with obtaining this material was the company changed policy as to min order. Bob used to buy it by the 5 gal bucket now they want him to buy a tanker truck load of it in order to get a price that would make every one happy. I used to live about 40 miles from Bob and his shop is not set up for that kind of bulk. I own a 20 oz and wish I could get other sizes as well. I see Bob a few times a year and I always ask when the next run will be ready.
Just finished this one for a person in Texas He is going to put his own silver on it. It fits a pair of 5 1/2 " Rugers and the loops are 45. I like to sew my loops on but he wanted them laced.
Try Bob Douglas up in Sheridan Wy. I sold him a a pile of parts that I had left over last year at Wikenberg. There were to or three shuttles in the lot.
