Sturtevant-Rich R600 beam wrench?

[gas guzzler]

I just bought one of these and was curious if anyone can tell me anything about this wrench? Original cost, quality, etc?

Also, I hooked this wrench to my new PI split beam and the Sturtevant is showing my PI to be a couple pounds off. Being how the Sturtevant is a beam wrench and I have the needle centered on zero, I assume it's reading accurate and that the PI really is off a couple pounds.. The PI is a 20-100' pounder and I tested it at 30 and 50.

Any thoughts?

Thanks

Truthfully, the "couple of pounds off" is probably within limits for the PI.

Make sure the top of the beam isn't rubbing the scale. When mine does it is a few # off. When centered exactly, it's nuts on. I have the 10-50 ft-lbs PI and the 0-75 ft-lbs Craftsman beam. They are both nuts on thru the scale, from 10 ft-lbs to 50 ft-lbs.

Do you ever send them in to be tested? I have a S-O 1/4" Dial that needs to be checked. Need to make sure them KB head bolts get to the correct torque.

The PI is new and as far as the beam wrench I don't think there's much that can go wrong with one of those is there? It was an army wrench but I'm not sure if they can be used enough that it will weaken or start to develop a memory or not.
