Thank you so much, Mark and Darren!
I hope to post again soon with something for you to review. Off to do some more research.....

: I think you did the right thing coming here first, plenty of
: knowledge here.

: I'm not aware of any British military issued Heuers, and even if
: that marking wasn't there, I would walk past that watch.

: Familiarise yourself with the OTD gallery of 40s watches:
: http://www.onthedash.com/Guide/_Chronographs/1940s_Chronographs/

: And take a look through the "Catalog(ue)" link at the
: same site. That should give you an idea of what the period
: Heuers looked like. Then feel free to come back here and we can
: comment on specific watches.
