This T-368 VFO / Exciter Module, was made by Veeder Root, and has a Form # A-148600 and P/N SM-D-361301 This unit is part of a spare parts group I have had for some time. This one looks to be in Very Good condition. It has all the tubes with the exception of the 6000 Tube. The Main connect plug is missing but they are relatively easy to find. It does have a Collins PTO. The Front panel is in really nice shape with a light scuff mark. I have not tested this unit and it is being sold as is as described for parts or repair.
