Hi-I think you have been maybe thrown off the scent by looing for 'Monza' parts. As far as I'm aware the Monza is identical to the equivalent Carrera 1153/1553, aside from the obvious differences. This means a signed crown and a Carrera crystal should fit also. Maybe that will help in the search? Both are parts that are available from time to time.

Best,
Steve
