it is a particularly nice piece isnt it Nicolas,
when the Antiques roadshow came to my local town when i was in wales i took
a number of pilots watches along and was actually filmed for the programme, but
was cut out before going to TV. the watch expert is a pilot so loved all the
pieces, nearly wet himself when he saw this and my laco B-Uhr.
perhaps its a good thing that it didnt show on TV as i wasnt very good at
being surprised by the value etc
sadly you dont see these pieces very often anymore.
