Lot of 11 Vintage Durant Manufacturing 5 Digit Rachet Tally Counters veeder root For Sale

Vintage Durant Manufacturing 5 Digit Rachet Tally Counters veeder root. I can't find any Tally counters under the Durant name. Two of these I can't find the name. Those are the two dirty ones. Not sure if I should shine them up or not. One looks like a 6 digit counter. I'm not real familiar with this product. But they are nice. A couple need some oil. They are tight. 6 are in working condition. Including the two dirty ones. The large one works great. Any questions please ask.
