Sorry for a late reply.
I had several brick amps for 2M that I acquired back in the day, I saw the name you posted and wondered if it was in my note book. I found the one I had with the notation next to it, Naval Electronics. I show I had one a long long time ago. I repaired it and I think that is the one that was made by World System's Electronic company, and the one I had which I think was their only one was a model WP-DX727.
I heard that it was made in Florida, but I don't have anything else about it. I checked to see if I have a copy of the schematic but I don't.
Hope this helps.
