There's still a lot of WS19s around, they are in regular use on the amateur bands and there is a WS19 forum on Groups.io which has around 2000 members. Vintage military radio gear like WS12, WS19, WS53, WS62 and other Allied radios can be heard on 3615kHz R/T most mornings around 0700BST onwards, if you don't have a receiver try one of the on-line receivers like The G4FPH 160 and 80 metre WebSDR Those in the photos are later versions where the UHF "B" Set transceiver has been removed, probably post-war rebuilds.
