No 18 Wireless mounting in Universal Carrier
 

I am trying to create a 'Wireless Set No 18 Carrier No 2' mounting as shown on the attachment. I can get a repro mount for the wireless set from WW2 Fabrications here in the UK but need to find the details / measurements of the Static battery mount and the 'table' described in the text to which both mounts bolt. I am assuming, but could well be wrong! that the 'table' then fits to the brackets I already have in my carrier shown on the attached photo. If anyone can help with any further details or measurements to assist I would be grateful.
Thanks
