Tim, I checked my 4200 also. #516071 Ribbed case, single screw cover. None of my Poulans in that series have the "grip safety" on the handles.
As for the Canadian built or marketed saws in that mid-size series, I don't have a clue. :msp_ohmy: All kinds of variations in those, even more so than the US marketed saws.
Just for my own curiosity, would like to see the lowest # and highest serial# 5200 & 4200 amongst us Poulan Nuts. Could be a decieving thing I suppose. They maybe didn't start at #001 or whatever.
Gregg,
I guess the throttle lock-out was made for markets where it was a legislated piece of safety eqquipment.
As far as the serial numbers go; my experience in manufacturing is that companies often set aside blocks of serial numbers for specific models or families that share the same similarites. That way there were never two different models with the same serial numbers but these block of numbers allowed easier ID if a recall came about. Still, we are around 300,000 + saws in that group just with the umbers a few of us have posted up.
Where the heck did they all go? Maybe there's an old warehouse around in the Texas desert with thousands of these in it.
Bob, get searching.
