Both 200t and 020t are open port. 200t is quad port, 020t is dual. It’s common to find an 020t jug on a 200t case. They are similar but not the same. 020t transfers come out of the case differently, so there is a mis-match at the lowers if you combine the two. Many people have run 020t jugs on 200t cases. They run well but some power is probably lost. Part numbers might tell you what you have or just lift the jug up and check. You may be able to see the transfer divider through the plug hole as well.
Looks to be in good condition either way. GLWS.
