Variometer mounting to underside of Aerial Base

[Patrick Johnson]

Hello,
I believe the attached line drawing image came from an ebay auction within the past year or so. Does anyone have a scan of this document at higher resolution? On my scan I can make out a description of the parts but not the actual part numbers.

Also included is a photo of some of the parts making up the 19-set Installation Kit for a tank. I am looking to buy the following parts used to attach the variometer to the aerial base:
1) Plates, Packing No. 1 ZA 2948 This is the thick rectangular plate centered in the photo, the Aerial Feeder Assembly No. 4 fits through the large hole and the small hole is for the variometer's guide pin.
2) variometer adapter washer, no part number available.
3) variometer adapter plate, ZA/CAN 1231. This is the square plate with the round hole, shown on the right hand side of the photo.
4) Also looking for two examples of the microphone loops shown in the attached photo
As usual, any assistance would be greatly appreciated!
Regards, Patrick
