[R-390] Dittmore Freimuth Filters:

[Frank Donnelly]

Good morning All;
    I don't post much, But read most of your posts. What a wealth of 
knowledge and
helpful members.
I have just come into possession of a Dittmore Freimuth  R-390A
Upon initial inspection I found the following:
1.  The IF deck "DAAB05-68-C-0040"  Has a set of Collins filters in it. 
S/n 34.
     Did DF  put out an R-390A's with Collins filters?
     I read some where that some of the early ones did have them.
     All the wiring around the filters looks Original. Very nice 
Professional wiring and soldering.
     So I don't think anyone swapped them out.

2. The IF,  2nd Osc, RF decks are the same 1968 contract number.

3. The Audio and PS deck are the 1967 EAC contract. "FR-36-039-N-6-0155

4. The front name plate and the rear chassis are the same 1968 contract 
number.

Being that It has Collins filters, my question is:
Do I really have an actual Dittmore Freimuth receiver?

It receives on all bands "Weakly"  I intend to restore it, but want to 
find out what I really have.
Hope someone can tell me a little more about it.
