What are the scale divisions? It looks like a vehicle scale. So it is most likely not in 1 lb divisions. Most around my parts are 10 or 20 lb divisions.
Crap!.... I didn’t think of that and I work for a gravel pit! I would change my guess to 1580 but jrider already took that so he is gonna win. But I’ll reguess 1570, if I can re-enter.
