Old-Biscuit,
Thanks for the information.
Do you know when they first started manufacturing this valve? It was on a tank that was made in 1948 making me think that the D8 could mean it was made as far back as August of 1948.
Not sure of date they started mfg. of that type of valve but Sherwood has been in business since 1890s
The business of 'compressed gases' came about in 1916 but really grew in the 1940s
