Lot of 3 Stainless Steel Elbows Schedule 80? 3/4" 304 Stainless

Description

Be sure to check my other auctions as I have other stainless steel pipes and fittings up for sale  on eBay. First I dont know anything about these. This listing is for a Lot of 3 Stainless Steel Elbows, I think, they are  Schedule 80? But not sure, if you know about these maybe you can tell by the pictures. Says   3/4" 304 Stainless on one of these.  I do know there are at least 50 years old because I have had them that long and my dad had them before that. My dad was a pipefitter certified welder from the 1930s to the 1960s and these were his so I know they are at least 50 years old. And they were built in the USA when things were built really good. So before purchasing them make sure they are what you want.
PS My dad was a top notch welder, he welded such things as cast iron engine blocks successfully and stainless pipe that weighed 1 ton per foot, the pipe was 30 inches in diameter and had 5 inch thick walls welded by hand and x rayed each weld, and it took all day to weld one v-joint
