The link you provided was for an Eico?

RCA used the VoltOhmyst name for a range of volt-ohm meters. Some different models had their own names like "Junior VoltOhmyst", "Senior VoltOhmyst", "Master VoltOhmyst", etc. Most were pretty basic VTVMs, although I believe there was at least 1 solid-state VoltOhmyst model.

The VoltOhmyst line were decent meters, I've got a few models I've (mostly) trash picked over the years. All worked well after replacing a small part or 2. I have some affection for the old buggers, but with limited space on my bench, a 410b is my VTVM of choice.

These were designed to be affordable meters for service shops and such, not high end laboratory equipment. The didn't have the high frequency capabilities of something like the HP 410b or the accuracy of the HP 412a. Basically, they were the Rigol of their day

Apparently the seller's lot has a mix of a meter and documentation that came from different meters. Anyways, indeed, there is a little trademark character after the Voltohmyst name, which likely indicates the name was a trademark, rather than a name for type of equipment.

Remember the Voltohmist series.
The Senior Voltohmist had a large, very legible meter panel. Very nice.

The only thing is that it took a long time to warm up and stabilize.

When RCA exited the test equipment business, a company named VIZ continued manufacturing them for a while until it went out of business. Digital meters were already becoming ubiquitous and the traditional VOM manufacturers which did not adjust simply vanished.
