Hi Folks-
Those handlebars were made from 1994-1999 by a private welder/fabricator in Washington state who had a small aftermarket saw parts company called "Pro Safety". He made those handlebars for Stihl, Husky, and Jonsered saws and also made the larger, more aggressive dawgs. Sadly there wasn't enough market for the handbars and he stopped making them. The USA brand full wraps are similar, but not as high quality and made from much smaller tubing diameter so that you still get white knuckle disease faster. Thanks, Jason.
