Sunward DUAL 38mm for 3.9" ID Tube Centering rings

I rediscovered the three centering rings from one of Sunward's Dual 38mm Engine Mounting Kit for a 3.9" ID tube. I'll likely never use 'em (I bought it for motor tubes). They're 3/16" birch ply, laser cut. I'm hoping to score some BT-80 and/or 3" OD (Estes PSII type) centering rings for them.

PM me if interested, or better still use my hotmail address (K'Tesh (minus the apostrophe)).

Pointy Side Up!

hmmmmmmmm I wonder if I dare...
