I have been offered 2 of these variacs, but the seller got no data on them. He sent 3 pictures to me that are shown below, the ruler used is a metric.

The coils resistance is 13.4 ohm and 14 ohm.

Can anyone identify these or give an idea of their current rating?

Believe it or no. Just yesterday i got exactly such NOS old variac. The thing is so small like palm of my hand. When i seen it i thought its some over sized pot :)

Mine is rated for 220 V, 1 A. I sanded it, cleaned and painted it black with compressor. If your is 110 V then probably not rated more than 2 A

Only difference is that mine has a vertical wheel as slider on coil.

good coincidence for me, thanks kreso

I also got worried about the size when I saw the pictures, since he said they were 8A or 10A.

Its 220/230Vac variacs, so 1A as your I would guess.

I need one for a MOT, and dont really know what use I would have of a 1A variac.
