[Collins] Seeking information on the 300 series Collins transmitters (1930's, 40's)

[John Hensley]

Good afternoon,
I'm looking for information on the Collins 300 D, E,and F series broadcast transmitters to include possible contacts with ex-Collins or ex-Continental engineers who maintained them as well as a picture or any in a service setting.  
I'm especially interested to find information on the 300F series.  Initially these were 250 watt transmitters but were possibly retrofitted a decade after productionwhen the FCC raised power limitations on some of the open channel frequencies.
If you have any original materials you could scan for me or sell to me, pleaseadvise.
Very 73,
John W5JV
