I just bought the Wright's newer (early 80's) Poulan cousin from ebay, and it arrived yesterday! This is the same as the saw we had at the lumberyard. It isn't as exactly like the wright as I thought it was!
Note the original butterknife-shaped bar. This must've been an early attempt at anti-kickback. No brake. Whoever had this saw must've not known you have to fill the bar oil! All around the bar, it's burned to HECK! It's been repainted, but man, is it whipped! Handle is cracked, but I found a place that has a brand-new replacement. It's plastic, but the main body (and shrouding) is magnesium cast.
