Hello Garai,

Your most interesting document raises several questions.

First, the four Ju188D-2 Werknummern in your document are possibly incomplete. My guess is that they would each be preceded by the numerals “15,” making them, 150576, 150580, 150585, and 150601. As such, they would fall nicely within known Siebel Ju188D-2 Werknummern. I am certain that one of our Ju88/188 experts will correct me if I am wrong.

My second question concerns the three Jumo 213A-1 Werknummern in your document: 103856, 103861, and 103872. None of the 183 entries in my Jumo213 database file take this form. Every 213A-1 in my file starts with a three digit number that indicates the maker (100 and 102 = Jumo-Köthen; 106 = Mittledeutsche-Leipzig; or 111 = unknown maker). This is followed by the numerals, “152,” and finally, a four-digit Werknummer. Typical examples would be: 1001520019, 1021520345, 1061521401, and 1111523825.

Any corrections or clarifications will be greatly appreciated.
