Another Ju88 plate
 

It never fails to amaze me the phenominal amount of knowledge held amongst members brains and books at 12O'Clock High.
Once again and with what I have been shown so far, can I ask for asssistance with the following JU88 plate:
Gerat Nr (Device or equipment number) 54739/11
Kontr 121
Anforderz 88.125-370
Hersteller (manufactured from) hln

The only link to a JU88 as far as I know is the 88 in Anforderz, but can anyone decode further than that? I guess its probably impossible to get back to a serial or werks number of aircraft from here?

Thanks - as always - for your invaluable help in understanding this fascinating topic.
