Help with identifying yellow Post hole digger

[Osutim1]

My grandfather gave me this post hole digger quite a while back, after it froze up and he let it sit out in the elements. He passed fairly recently, and I would like to get it going again. I am leaning towards a Land Pride PD series, but that's just a guess.i have it torn down and need to order some bearings and seals and a few other items and need to figure out the brand and model if possible. Any help would be greatly appreciated

I guess you arnt reading any numbers off the bearings or seals?

Can't make out any numbers on them, they are in too bad of shape, I tried.
