Olde timey draftspersons: Where to find this eraser dust mini-vacuum?

Somebody once gave me a tiny vacuum cleaner that could sit in the palm of your hand. It was essentially a red plastic cube about 2.5" x 2.5" x 2.5" with a hole in the bottom and a rocker switch on top. It’s bottom edge was ringed with little brush tufts that kept the device raised off the page about an 1/8". The device was intended to gently suck up eraser dust off drawings. It was marketed to draftspersons, achitects, artists, etc. and was sold (I suspect) in the 1970s and 1980s.

I never used it, but I gave it to my then-GF who was obsessed with food crumbs. She loved it! Worked like a charm.

I just reconnected with the exGF recently, and she said the little vac had died a while ago and she could not fix it, so she had to toss it out.

I’d love to get her another one just like it. Any ideas? I’ve found similar items on ebay and various websites, but nothing that is an exact match (okay, it does not have to be red, but I want to get the same model and brand as the original).

Thanks all, in advance.
