Hi Jan ,

1. The Monaco was powered by the Cal.11 movement from '69 . At some time around '70-'71 production was completely changed oved to Cal.12 movements.

2. The Silverstone ( being produced '74-'78 ) was never officially powered by the Cal.11 movement.

Naturally over the years some examples have surfaced to throw both of these theories to the wind, but i feel its more likely to be replacement movement, service and parts bin pieces that swim against the tide.

Hope this helps you.

I've been keeping an eye out for the parts and piece's you're after but no luck yet. Maybe its time to place a WTB listing in the Chronotrader section.

Nice that the weather has turned around a bit (not frozen) - i'm back to riding my bike everyday now ;-)

All the best - Darren
