[ICOM] Query: 1st Icom HF Transceivers ????

[Jan Robbins]

A collector friend sent me an email with the following interesting Icom 
queries.  I couldn't answer them. 

1)   What was Icom's first amateur radio HF transceiver?  When was it 
introduced?

2)   What was the first Icom transceiver sold on the US market?  When 
was it introduced in the US?


Can anyone help? Any info greatly appreciated.
vy 73 to all, as always!!
