For info - solved by the guys on uk.d-i-y....
It is a depth stop. Once I had the thing in
place I was amazed at how simple it was
to adjust and how well it worked.
Just slacken off the wingnuts and screw
the guide up or down as necessary.

Interestingly I was in Pennyfarthings in Salsbury(UK) - they
deal in all sorts of old tools... I had these items with me
and asked the guy in the shop if he knew what they were.
He had no idea. Anyway, I browsed round the shop and
there in a cabinet were the very same items! With a tag
saying "Adjustable Bit Gauge - £9.50". Unfortunately no
one in the shop (owner away on hols) was able to shed
any light on what they are for.
I will return in a few weeks time and discuss with the owner.
I wonder what an Adjustable Bit Gauge does... Hmmm...
