Scales Wanted.
I had an extra one that I gave to the cub scouts to weigh pinewood derby cars. It weighed in grams which is the standard measurement for engine parts.
It is also used for gemstones weighing in carats. I think I paid around $75 for it. If interested I will see if I can get another one. I looked around my favorites list on 2 computers and I didn't save the site. I may find the invoice though. Mike
