just out of interest
when I sent my Reuben Heaton specimen hunter millennia scales away for a service they check weigh them on arrival and again after the service and give you a printout
I was so pleased to see the accuracy from scales that have been well used since purchasing in year 2000 was pretty much bang on maybe 1 ounces light above 50lb prior to service
I then got my weigh tripod out and a 5 gallon water carrier and checked them against the Wychwood t-bar scale I had bought with measured amounts of water again delighted to find the Wychwood digital scales were reading the same though out
I would recommend anyone with an old set of Reuben Heaton scales to get them serviced by them rather than buy new as they will come back like new as they replace the case as well during the service
