I got to Udorn in August of '73, and all nose art and unofficial markings were gone at that time. By the time I got there, Udorn and Ubon were phantom bases, and the thuds were at Korat and Takhli. Eariler they were switched.
I seem to remember that the 119 ECM pod didn't have the very bottom short gondola under the front. I dropped one off a jammer one day and ended up on top of it. Shattered all 4 of the black radomes....10k each at the time, and scrambling a bunch of circuit cards in the long gondola. The final bill was around 240K, IIRC.
The bottom bulge is a later mod to the 119 family.
Was an ECM tech, we had 71's, 101's, and the 119's, and got all of Ubon's 119's and equipment when they started to close out operations in '74.
Don't know if your a/c had the color flash on the top of the vertical stab or not. Ours were by squadron (I think), red, white, green, blue, etc.
