JU 88 A5 Werk-Nr. 6239

Hello from a new forum member. I have enjoyed reading this forum, but now have something to ask.
I have what I believe to be the (rather battered) makers plate of the above aircraft.
It belonged to my father, who was in the SAAF during WW2.
Although he was too young to make it to front line service, he became a w.o.p. air gunner in Ansons.
I recall him showing this to me in the late sixties, and it recently came to light again.
I suspect that it was a schoolboy souvenir, as it was in a box with other school memorabilia. He lived in Cape Town.
He had two uncles who were in north Africa and Italy, both in the SAAF. His father also served in N Africa throughout the war, So it may have come from there.
My father had no involvement with aviation subsequent to his demob in 1946.

The details on the plate are as follows:
Junkers Flugzeug- und- Motorenwerke AG. Dessau
Muster: JU 88 A5
Werk-Nr: 6239
Abnahme 28.12.1940
Heinkel- Werke G.m.b.H
Oranienburg

I guess the a/c might have been made by Heinkel under licence, or modified by them perhaps?

I have done some searching on the web, without finding out any specifics, does anyone have any records which may shed some light on this aircraft’s history?

I am intending to attend the Shuttleworth engineering open day, and could bring the plate with me.

Cheers,
Charles
