Safe to say you are well in the triple digits then?Oh man... whatever guess I'd make would likely be way, way off.
Actually the bar is damn close to 30 years old, when I say 22 years that's just the current saw... it was used on an 024 for a few years before I traded it for the 026.
Let me tell you how that went... in the 80s I bought a near-new-lookin' 028 with a 20-inch bar from a guy who's truck had broken on the road and had it towed into our shop. He and his crew ended up spending a few days at the motel while we fixed it... by the time they paid the bill(s) they'd run out'a cash. He (they) needed gas money to get home... I'd spotted the 028 in the box and asked about it. He walked over and pulled it from the box, started it on the second pull, shut it down, set it at my feet and said, "Hundred bucks?"
So after I'd used' it for a year or two dad borrowed it one day, hooked a fence, and promptly broke the crank. I hauled it into the saw shop and traded it for another 028 wearin' the 16-inch bar, and I kept the 20-inch also. A few years later ('92 or '93) I traded the 028 power head for a lighter, brand new, first year, 026 power head... (i.e., I kept both my used 16 and 20 inch bars).
That 16-inch bar has cut a lot of wood... there ain't one single speck of paint left on it and it's worn down to the point where the drive links almost bottom-out in the groove.
It's time...

I'm retiring my 16" bar shortly also...it cuts crooked. The rails wore out long before the replaceable nose did.
