Here they are. Pardon the dust, I didn't realize it was that dusty until I looked at the pictures. I took all the pictures the same distance from the panel so the sizes should be relative to each other with the exception of the OX Gage, Blinker, and Oil pres which are on a sub-panel which was a little closer so they appear bigger. The smaller ones are 2 1/4" and the larger ones are 3 1/8". The gyro horizon and gyro compass are odd sizes I can't remember off hand.
