Unknown item in W&B

[JimC]

I'm looking through my old W&B docs, and I found this line item in the original factory W&B:

"MODEL 337TURBO SUPER SKYMASTR" [sic]
Weight: 159.0 lbs
Arm: 115.5

The airframe itself is listed as "STANDARD AIRPLANE (EMPTY,DRY,UNPAINTED) ACTUAL" with a weight of 2617.5 and an arm of 141.6.

Does anyone know what that 159 lb item is? Is that the factory way of listing the turbo system? I find it odd that they'd build it, weigh it, and *then* add turbos.


At some point my c.g. jumped over an inch and a half forward and I'm trying to find out when & why. It's currently 137.5, which seems VERY far forward. I go out of c.g. with two people and 1/2 fuel. It's been as far forward as 137.2, which seems to me to be dangerously far forward. It came from the factory at 138.9. The w&b that moved it from 138.9 to 137.2 is missing.
