Gents may I ask you for any details (pics/height) of that (rubber I guess) mounting under the aerial base as on the pictures (thank you Ron). Part is on the position 26. Many thanks!

Camera is down right now, but thickness is 24.25mm. Have a NOS one sitting here.

Helo Petr, I have spare one I think. Do you have any Carrier parts you could swap?

Regards,

Tom

The spacer was made in a variety of materials, presumably down to what was available at the time/place of manufacture.

British ones are/were made of rubber (I've seen white, brown and black examples).

Canadian ones were made of plywood, with cork gaskets glued to top and bottom in order to keep water out.

Post-WW2 (possibly later WW2) British ones were made from steel stampings, as two shallow dishes welded together along the seam, and rubber gaskets were used (which continued into the Larkspur era with a variety of bases).

Best regards,
Chris.

Thank you all for the detailed info! So it looks that I will need rubber one for the British carrier.
Is it made just from the plain rubber or reinforced rubber, please? Any pics?

Just a moulded rubber block, but it's "stepped" inside to clear the central insulator or connection post.

It shouldn't be hard to find one, I'm going to Beltring this week and will have a look around.

You may also need the connector plate, and there are two varieties - I can't remember the stores codes at this time of night - one is for the "early" connection and is just a disc with a central insulator that takes a ring terminal on the underside and an aerial pigtail on the top to connect to the base (No.8 or No.10). The later version for coaxial cable feed has a cable clamp (like the Pye elbow socket) underneath and a pillar that takes the coax centre and the pigtail lead. For the co-ax version there's also a different feed plate for the back of the variometer.

Best regards,
Chris.

Thanks a lot, Chris!
Edit - so I think I will need something like this (photo from Tim Bell - thank you)? Bottom middle
