Some eight inch computers have price wheels. I you find one do not let that stop you. The six wheel faces will still screw on and cover the price wheels or you could remove the price wheels. I have a Tok 34 that was original unrestored with six wheel faces. When I took them off there were price wheels behind them.
Had a chance to check our VR's today. They look like the 56A model from above link and have been reconditioned and maybe one or two hasen't. They all measured 8 inches across the front on mounting brackets and 12 inches on the sides. There is a tall Tok 39 there and is same as in it. So kind of looks like a match for lots of pumps. Only one VR is 4 wheel on top row. Make offers and would like to sell all at once, 5 V/R's and 2 Neptune Auto Stop model432 truck dely meters. We're in NE Wis and snow is in the forecast, they are inside out of the weather.
