I've an old Holloway that's very similar to the Minitex.........probably a bit heavier. It's been lying in it's little box in a corner for the past couple of years. I took it out a couple of days ago and it's working fine. Comes with two brushes.
I got it for Hotel and Restaurant work a while ago but no longer do that kind of thing.
If you think you can use it, give me a call.
