I am not an expert, but I think the moon disc seems to be from a later model.

 

I have one very similar to this one, nice looking UG Tri-compax, dial is very nice, all the moon discs look the same to me on Tri-compax, but there may be some varience. Overall looks very nice, for a steel UG Tri-compax the price seems a little on the high side. Troll the web and the bay I
I think you can find a similar one at a better price! Good luck hunting!
