Re: BTH C2 horn speaker
Excellent job Vince!
Depending on the logo design, you may find that you need white rather than clear water-slide ('decal') paper. I recently printed some 'top labels' for the Wartime Civilain Receiver cabinet on clear paper. They looked fine when on the backing paper, but very poor when slid from the backing paper and applied to the top of the radio. I reprinted them on white water-slide paper, and they turned out fine. Can't attach a pic as I'm away from home till tomorrow. Every success.

Re: BTH C2 horn speaker
Brilliant job Vince!
The (rather battered) BTH logo on my example is in black and gold on the horn inner, 17mm dia and on my example its centre is 80mm from the lower rim of the horn. I attach a photo. Martin
