Anyone here own a Marvin vertical milling attachment?

[VSAncona]

I have an incomplete Marvin vertical milling attachment for my Atlas MFC milling machine. It’s missing a couple of the pulleys and possibly some other parts. I was wondering if someone here who has a complete attachment might be willing to help me figure out what I’m missing and maybe give me some dimensions so I can make replacement parts.

looks like 2" B pulley's by assumption

Thanks Ulma Doctor. I did see that, but am looking for some more details on the dimensions and the shaft. I’m missing everything that goes along with the idler pulley. Also would be helpful to know the belt length.

hypothetically,
the shaft is 1/2" diameter x 6" long
pulleys are 2" diameter 1/2" bore on the idler
drive pulley 2" outside diameter, possibly modified drive- MT2 to threaded /keyer adapter to match pulley bore of choice- if nothing else is available
i surmise the belt to be in the 30" B - range
(the one picture shows a Gates 7300 belt, that is the equivalent of a 30")
