Wife bought me my first at a used tool store, turned out to be a cast iron aso but thats ok, She bought it for me, I'll keep it.
Found my second , a mousehole broken through the hardy hole at a scrap yard, 127# for $100. Got my third at a farm store, it was on commission, a 75# Lakeside in very good condition. Paid to much but I really like that anvil.
