Short Wave Receiver and Detector TRD-1

• Marke: Telmaco

(Telmaco) Telmaco TRD-1 is the TR-1 Short Wave Receiver and a Detector combined into one quarter sawed oak cabinet. This kit was completely assembled but sold unwired.

The well known book "1921-1932 Radio Collector's Guide" by Morgan E. McMahon lists on page 171 for Telephone Maintenance Co. (Telmaco) the following models: 1921: TRD-1 (no price); 1923: Telmaco (Reg. for $ 25 and we assume model B-R), followed by 6 models P-1:
1924: Telmaco Acme P-1 (we call it "old" for distinction to the "new" Acme portable);
1925: Acme P-1 ("new" Portable) for $ 125, P-1 ("old" Portable) for $ 147, P-1 (Kit "old") for $ 85;
1926: P-1 ("new" Portable) for $ 125 and P-1 (Kit, "new") for $ 80.
All these models with P-1 are shown as Reflex with 3-3 stages and one "Big tuning dial" and four tubes for batteries. It may well be that in this entry there are errors, for instance no distinction between model "old" or "new" or both kits are the same, but as a reference work (not a catalog!) we have to show all of them and to explain.
