Moore G18 jig grinder.... where is "spindle" speed info ?

[Milacron]

I've got this one on eBay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200333178324&ssPageName=ADME:X:AAQ:US:1123 but there is no spindle speed stamped anywhere on the pneumatic housing...was there a sticker that fell off or is the speed perhaps stamped on the inside of the housing somewhere ? Can anyone tell just from the physical size what RPM it might be ?

Cant tell from the picture,but,if the motor has a 3/8 hole in it for the wheel shank it is probably a 1 HP head that runs at 40,000 @ 100 psi. If its a 1/4 hole its for smaller holes and runs @ 60,000 @ 100 psi.

Gotta love the Maho in the background of your eBay photos, showing you are a caviar-grade "pre-loved" machinery dealer!
