Hi,
What dimensions/specs do you need?
According to my (not calibrated) micrometers my:
22mm arbour is Ø21.993mm (measured with mic)
27mm arbour is Ø26.99mm (measured with caliper as I can't find the 1-2" mic)
16mm arbour is 15.993mm (measured with mic) — mic starting to warm up in my hand so most likely this is under size
They are old and I can't be sure of the level of wear from use over the last 60 years.
The spacers are bored ~Ø0.05mm over size. There is play if you try and wiggle them.
The bearing support bush end piece are a "tool makers fit". They slide on nicely but there is no play felt. And of course the retention threads at the end of the arbour and nuts are left hand thread.
Why don't you get the specs on the tooling your buying or measure what you have? I have no cutters for them. (I only have 1" diameter tooling) so can't measure the ID of the cutting tools. Hence they will now go back in to storage.
