We have had it for YEARS! Being the children of depression era parents, my wife & I almost never throw anything away
It was the pole for a cat toy, The nice thing is it is hollow, so is very light & is 27" long, allowing me 3" for attachement & 2' above the sled.
Sorry that isn't much of a help. BUT, I have seen similar toys since this one was bought all those years ago.
Sure, Doctari - you stick with that story. I'll bet you lifted it off a wheelchair on one of your runs.
