Thanks Jim and Don,

BUT, where do my RCA Global Model 15's fit into all this?  They have rotary 
dials on the accompanying box and a telephone line connection...2 wire.

Did RCA Global have the international business? Or, did they compete with 
W.U.?  I think my RCA Model 15's deserve recognition in this discussion  LOL
