3 pieces of TR equipment!

[LizardKing]

Hello all!!

I've found some items of the TR era that i know absolutely nothing about them and i seek for your help!!
I'm posting them together in violation of the forum's rules but i think they are of the same area of equipment so i might get an answer for all of them at once without fulling forum's space with multiple threads!!

Thanks for your time and help folks!!

First is this beautiful wooden box!

Hello Glenn! The lectronic relays are the two metal or the two wooden items? And when you say 'marked suitable for tropical service' you mean there is an inscription that says so? If yes where is this?

The bottom two wooden cased devices are for connecting single to double lines and field phones to civilian and postal lines or for isolating phone lines from heavy RF interference. The official name is Der Übertrager. In English I guess we would call it a transducer. Photo shows one with the leather transport case. If you want to sell one I am interested. Another source for info on this device is der-Fernmelder.de NH
