[ARC5] [Milsurplus] No GO-9 On Display. Likely GO-2.

[COURYHOUSE at aol.com]

I like photos like this  to show how things were used in the plane. It  
adds  to the display.
 
Guess I need to get one of those  little freq meters! was   tat  called a 
LM? I used to see those all over the place ....

Meir,

The photos in  that cutaway have intrigued me for several years.

The GO-series  transmitter pictured is definitely NOT a GO-9...there's not 
a bit of doubt  about that.  So...wbat is it???

There were only four makers of the  GO-series:

Hygrade Sylvania
GO       1933

Western Electric
GO-1    1934
GO-2     1935

Westinghouse Electric
GO-3    1937
GO-7   1940
GO-8    1940
GO-9     1940
GO-9a   1944

General Electric
GO-4     1938
GO-5    1939
GO-6    1939

If the photos  are enlarged and studied, the largest lettering is the 
manufacturer's name,  which appears to be the stylized "Western Electric".  The 
cutaway likely  has a 1935 GO-2 installed on a 1943 PBY-5B.

That's not so  unlikely...the website explains that the aircraft was 
damaged in 1944 and  subsequently turned into a non-flying training exhibit.  It 
would be very  possible that older gear would wind up replacing a set that 
was currently  needed for flying service.  The preservation of what is likely 
the only  surviving GO-2 is a happy consequence.

For similar reasons, it is  uncertain that the receiver system is actually 
the expected RU-19  system.  There would only be ONE RU-19 system with its 
TWO CW-46048D  receivers.  Regardless, the liaison-service receivers RU-4 
(1935) through  RU-19 (1941) are visually and electrically essentially 
identical.

I've  been wanting to make a trip to see this cutaway and try to verify 
what is  really installed.  One thing is certain...there is no GO-9 there.   :-)
