Hi,
I bought one British made last year with obviously such missing ones, (not falling from the body either Mark!) and was also prepared to work there. Then another one presented itself (US made) cheap here in France. What could I do? I bought it and it happens that it's working fine. Even the plastic gears are good. So I neglected the other but I will do it. They are wonderful stuff. Mine have both the 1 GHz option.
Do tell us how it's going Mark
