Dear John,
I made one myself, from oak wood, darkened and oiled. Will send you some pics later.
The replicas from niemoeller are really bad. Simply a 2D cut-out, and not even close to original hand made version ;-)
If you are interested I'll do one (a copy of the one I did for my own 170S) for you. 75 Euro + shipping (from Sweden).
Please send a pm, or simply reply in the tread :-)
Wishing you a nice day!
Thomas
