Ah yes, I spotted these about half past ten last night.

Both previusly unkown to me & both rather interesting! The Dingwall is only the third example known to me

whilst the electric is a Carter & looks to be a Model E, again only the third Model E so far known.

Its certainly not 100 years old, but it COULD be very tail-end of the 1930s, or more likely late '40s.
In the past few minnites I've just got off the phone from the seller. I'm off up to his place tommorow to have a closer look at them....
