That regulator was made by Marshall Gas Controls, which has been out of business for several years. There was never any connection with Marshall Excelsior, but our product line is very similar to what they had. The current MEC replacement would be MEGR-295. It comes with the brass POL adapter already installed in the regulator inlet. Any regulator should be installed with the vent pointed downward to keep moisture out. The MEGR-295 has the vent positioned 90 from the outlet instead of directly over it, so it is pointed downward when installed horizontally. Here is a link to MEGR-295 on our store https://www.rvupgradestore.com/Two-Stage-Side-Vent-Propane-Regulator-p/06-0447.
