Hi Ed. Yes, certainly agree that typically an aspirator powered by manifold vacuum is what was common for quite some time. It is important to note that while some ambulances had the cylindrical vacuum reservoir - some did not. The contemporary installation instructions do not require it. My Pinner-Chrysler had a Rico RS-4 from the factory without a reservoir, my 1970 C/B Olds was similarly without one, and the Violetville Carryall I just posted a photo of did not either. Wasn't specifically referring to my Hi-Boy - but it's possible there was a Rico or similar. I'll be starting to post more neat articles from that archive soon, plus I ended up with a selection of 1950s/1960s rescue/ambulance manuals which have been illuminating with some great equipment lists and photos!
However, the topic that was of interest to me and posed to the group was:
1. Alternatives to the Rico, like the Violetville one had. Interested in seeing any photos that might exist showing similar elsewhere, or whether it was just a local thing. Rather ingenious!
2. Electric powered suction units like Gomco and Sklar, particularly since the Violetville's on-board system appears to have been cobbled together with parts from an on-board aspirator, how common were they before the introduction of the Laerdal Suction Unit (Gray Case) in the very late 1960s. While theoreticaly possible with inverter-equipped ambulances, reviewing a large quantity of available stories on Newspapers.com - the only thing referenced with inverter-equipped ambulances are "Rescue Saws (Just regular Sawzalls, apparently) and Incubators. I've tried to dig up every "layout" photo I can - and never seen one there either.
