How can I tell what geometry this cartridge set-up tool uses?

[nmtjb]

I have this old Pluto gauge and have used it a few times to set up cartridges with its simple alignment grid and it seems to give decent results with 9" arms. The Feickert tool has Baerwald, Lofgren and Stephenson options, and I'm interested to know what this tool is set to. I assume, probably Baerwald but is there a quick, (simple for me) way of checking?

I've emailed Pluto but no reply and can't find any online info for this particular tool.

Measure the centre of the spindle hole to the stylus cross-hair. That will almost certainly show it to be either Stevenson or Baerwald (60 or 66mm IIRC).

Great thanks Tony, 66mm it is.

Contact Disney, Pluto still works there.

How long have you been walking around with that chestnut in your pocket?

Sperm of the moment, no malice aforethought.
