53", .404", 063, D009 mount also called UAO.
Doo9 is a large mount Husky...9.5mm. Unless it had sloppy machining, it would require some milling/filling to fit an old J'red. Rather than do that, I'd use it on my Husky 2100. I don't have a J'red anyway that would run that...you'd need the 111S or the 1020.
It's just fantasy anyway, because for the price of getting it over here I might be able to buy two Cannon bars. Quality-wise, you're not gonna beat a Cannon professional bar. From the pic in perspective, I would have guessed that bar as a 48"!
