Exotic TELEFUNKEN 439 U (Without ”T” before the ”439 U”) Made in Romania ?

Good Afternoon

            In Romania there are to be found very peculiar Telefunken receivers marked TELEFUNKEN 439 U (Without ”T” before the ”439 U”) with the rear lid inscriptions printed in Romanian language, containing inside only a regeneration stage followed by two audio frequency stages (NOT a superheterodyne like TELEFUNKEN T 439 U). They are equipped with CF 7, CF 7, CL 4, CY 1 and an Urdox.

TELEFUNKEN 439 U belonging to me.(Still in restoration.)

TELEFUNKEN 439 U belonging to a (romanian) correspondent, Mr. I.C.

 

            I would like to post a larger description & schematic hoping to find people who coud provide more information about Telefunken receivers produced abroad. (Outside Germany maybe Romania?)

            My problem is I do not know where to post all that. Could you please indicate me how shall I proceed?

            With best regards,
