LF 1/50 Heller JetRanger parts

[KiwiZac]

Hi everyone,
This may be a super long shot but, given Heller can't help, I thought I'd hit up my regular hang-outs!

A friend sent me a Heller 1/50 JetRanger I'm dying to build but a few vital parts are missing: 37, 39, 40, 41 and 42.

If you can help at all - and are happy to donate any of these parts or accept an IOU as I'm not in a position to pay any time soon - please get in touch!
