Looks like old Heath Kit servos with the mounting tabs cut off and the liner output arms removed. They were called KPS 9 servos when they were made by Kraft.

Could they also be World Engines servos? I have some old ones that look like that.

By color and approximate size those could be Kraft KPS-9 servos.

If true, then they would have both linear and wheel outputs on the side the photo necessarily blocks out .
The case color also could be World Engines, as previously noted.
While Pro-Line used Kraft mechanics and that color case I believe theirs were all KPS-15II mechanics.

First of all i want to thank everyone who has replied with answer's to little delima , I have looked up lots of info and pic's of these servos and it appears this particular style servo was used by many early co. even found an old cannon setup that looked identical ,also found a kraft gold series with from what i could see these servos and i looked for slide slots on the side but did not see any ,there are 4 flat head screw's on top and 2 in the center of the bottom ,the kraft i have found look identical except for the fact that they used phillip's head screws from what i could see ,but none of these setup's had the plain white receiver box that i have so im going to concetrate my search on the receiver because it seem's to be less common ,once again thanks to all that have chipped in to help as i said before they are setup so well and excellently placed and for nostalga purposes i want to locate a transmitter to go with my restoration of this super example of an AMERICAN RC REVOLUTION and where it all came from.Thanks

Man, your remote control looks just like mine, but I use mine on my Dish TV receiver, not on my radio control stuff:-)))))))

Definetely Kraft KPS-9, also used by Heathkit, and any other after market outfit that could use them. There were not too many manufacturers in those days, and Kraft supplied the majority of the Military RPV control stuff. How do I know. My son went to school with one of the Kraft Engineers that lived just down the street from us, and we got to be quite close acquaintences.

AS far as the remote it's all in how you wire it . Thanks Chad

Your welcome.

Unless things have changed greatly while I wasn't watching, the pulse timing is still the same, and the only important thing is the information transmitted and received. It doesn't make any difference how this is accomplished.

Once again we are thinking alike ,the crystal reads an odd # of 36.7065 whick in my endless bag off antique crystals that i bought for 10.00 from my l.h.s I have no match ,now I assume that im dealing with AM and i want to solder in a matching set of AM futaba crystals and it should be a go right ?
