19-Set Vario/Aerial Base Mounting Plate

[Patrick Johnson]

Hi David,
As the owner of the WS19 set pictured above I can shed some light into the plate's identification and how it is fastened to the Transceiver case. A look on the underside of this plate yields the following original description spray-painted on the right side of the plate: Plates, Mounting No. 1 - ZA-10465.
On the top of the Transceiver case are two rectangular registering plates, each comprising two sets of three holes in a V-shaped configuration. Correspondingly, on the underside of the mounting plate are four "saddles", each holding a small threaded bolt with a clever retaining ring which keeps it in place. On this example only three of the original four mounting bolts remain, so at some point one of the bolts was removed and never replaced. The saddles with their extended bolt heads register perfectly with the middle tapped hole in each of the four mounting hole groupings. It's a simple operation to hand tighten the bolts into the top of the case, until the final couple of turns when a wrench would be used to firmly tighten down the plate to the case. I've also photographed the monogram found on the bolt heads holding the aerial and Variometer in place, as well as the small round black ink stamp of unknown significance. To definitively answer your question David, yes, the right 1/3 of the plate is truly cantilevered beyond the registering plates of the case.
Hope this helps,
Patrick
