I think I have seen a picture of one before but I can't find that part of my memory at all. I don't think they are rotaries to be honest.

I saw them on eBay and have won them.

I want to say it is a very early pen type machine, however with a vertical slide that travels through the solenoid. The slide or piston holds a cut down needle bar and I believe it uses a special autoclave able tip/tube and I think the slide is clave able too. Like I said I saw a photo or ad for them once some years ago but I don't know who made them or anything else. I would really love some help.

Sorry for the poor photos they were the ones included in the ebay auction. That I might add was worded with almost zero information.

I believe I once saw a photo of someone tattooing with one that was dated in the 70s or 80s, I am assuming that they are older creatures.

Thanks in advance. I will update when I receive them.
