Oh, yeah ... a couple of days ago I found something I've spent over five years searching for: A Hydro-Vac brake booster filter adapter that about as close as possible to the OEM adapter. It's a new adapter, made to fit the Fram CA2PL1 (or equivalent) used on the boosters in early motorhomes. It's a regularly manufactured and stocked item, as opposed to one-of-a-kind items.
Details to follow in a couple of weeks, when I've gotten my hands on one and established what's need to replace a missing or badly corroded adapter. I will also discuss things to watch out for to ensure your boosters keep working and last a long time.
