I read it as Sk WINDER, the helicopter recovery one.

Not the Sidewinder missile.

I hope that's correct.

Now believe it or not the body tube may be a problem. Not a big one but it's not just a BT-20. it's very heavy walled but I think it can be duplicated with a BT-20 filled with a full length tube coupler.

I have a few full length BT-20 tube couplers and lots of BT-20's.

Let me fool around with it. This is doable but I'll wait until you let me know for sure what you need.
