need to identify manway type on pressure vessel circa 1945
(OP)
Have a manway type on an old pressure vessel that I do not know the type. It is 2 piece. the insert is the sealing part. The outside ring has the bolt circle and tightens to make the seal. The vessel was constructed in 1945. Just need to know what type manway this is.

The claves were designed by DuPont and if I recall correctly some were built by Downingtown Iron Works.
