Yes Hello and Welcome.
Like most Forum members we all have our areas of interest, Mine (our) is the restoration of a 1963 BBC Television Outside Broadcast Van. (Google MCR21)
We need to find a few items in the vintage electrical category. Two Ventaxia domestic fan speed controllers are high on the list! The part number may be LOTEL CF59V, and two are needed.
We are looking for the exact type to be historically correct.
Also sought, and harder to find, is the fan itself. These are military ones from the 1950s this one is a 240v AC. version, many were 24V DC ones.
On the catalogue front a period Ventaxia (1963) one would be good to add to the records.
There is a LONG list of wants at
