[R-390] R 390a Dittmore-freimuth

[mparkinson1]

This item is up on ebay and if I recall right the modules should be marked Dittmore-freimuth not EAC. 
Can anyone shed some light on this I think the seller is reading the tag and selling it as a Dittmore-freimuth  receiver. 
I remember one being sold and all the modules were marked 
Dittmore-freimuth 
Am I correct???
