relic unknow

[Dan Gilberti]

Hi
I need help for identified one Lw material .
Note this relic was found by one friend in camp of "Parthey" near Dole-Tavaux airfield in France .
The history for this camp is a mistery : perhaps this camp was used by german's (barracks and mysterious relics) for one Aid approach system for the Nightfighters from 6./NJG4...
Perhaps this discovery can help ?
16,5 centimeter diameter ...
Thanks by advance

This appears to be an unused chart from a machine that would record most likely temperature or barometric pressure. A pen would make a continous line to indicate the reading. A full circle around the chart could be a day or a week.

The inscriptions on it are:
Welle (Wave)
Datum (Date)
Flugzeug (Aircraft)

Which seems to indicate it was used to plot possible attack waves, either those attacking or those sent out to attack from that specific point.

The theories about this item are interesting. Attached is the envelop that these come in. My German Dictionary translation is: Accessory for Radio direction indicating apparatus 3 - Deviation curve full plate.
This went into the rear of the large repeater compass carried by most mult-engined aircraft. A pin would scratch the trace into the painted surface for a permanent record. The markings on the plate go from 0° to 360° with deviations from + 30 to -30

Many thanks
With your help,I have found the datas in Funkbase Aichner :
FL23475 127.117.130 Funkbeschikungsvollscheibe für Funkpeilanzeigegerät FL 23470 .
No, chance for me it's one ordinary teil from Lw aircraft, nothing common with my mysterious station approch ...
Best regards, Dan
