I am working on a vacuum control project and I need some advice.
Does anyone know:

- What are the sizes of the three bleeds used for intensity setting
of '2', '4', and '6', in the Ampico B?

- Were these bleeds pre-sized as cups and fitted as a standard part,
or were they sized to be on the small side and opened out to suit
each individual stack?

- Were the bleeds made of the usual brass cup technique?

Thanks for any advice.
