not ebay, but here's a nice A3637. Reasonably priced considering it's dealer IMO.

An A271 with a telemetre: not seen one like it before, is it a known variant?

The heavier weight on the subdial printing suggests to be it's been refinished, along with the different font for the 6's... But the telemetre font and weight looks spot on.
