Unknown item in W&B

[JimC]

BTW, I found all but one of my missing W&Bs. The one where the weight seems to "jump" forward is a reweighing from about 30 years ago. The weight and c.g move as though 111.5 lbs were added right about at the pilot's knees. That's a lot of "found" weight, and very far forward. Every W&B since then has been a calculation off of that one.

I don't think the 1990 reweighing was done precisely.
