Heres a wrench thats new to me. No P-31 Perfection wrench. Really feels good in your hand,almost makes me want to turn a nut(almost I said) Alloy has a smaller brother listed and say it was made by Duro for Western Auto. This one is 7/8-13/16 and is stamped Chromium Vanadium on other side. Think I,ll hang it in the basement next to my other Duro-Indestro stuff.
