I just aquired this desk top phone and it is compelely different than all the other phones I have researched. It is marked on the perch back 20BC which is crossed out. The 20BC should be brass nickel plated, this is not. On the perch side it is marked 20AL and all information so far on the 20AL is that it never was produced just in brass. It has a Stromberg-Carlson receiver and a 337 transmitter.
