Scrach - a great harness for the Falke is made by RB Productions - check out the 1/24 Luftwaffe Seatbelts here:

Shipping is more than reasonable to the US
Here's a good build thread for the Falke and you can see the harness in action.

Jim (Papermodeler), don't know why I didn't think of that...
Daf, I think that will fit the bill just right.
Btw, have you tried the Scribe-R from RB? It is the best thing I've ever used for scribing!
Thanks for the link to the Ma.K forum, now I REALLY have to control myself after seeing that sweet Falke build.
