Any ideas for ID'ing this motor?

Hi group,

Just came back from a local industrial salvage yard. Picked up an olde
mainframe computer tape drive - remember the ones with the large reels and
vaccuum tape handlers? Well, I liberated the rather largish reel motors.
They have no manufacturer named on them; they have some miscellaneous
numbering and say "50 volts nominal". They are 7" long by 4" wide.

Anyone seen this kind of motor before? Any idea what kind of current
requirements these beasts have? Will they overload my Gecko 320s even
though I have 5A slo-blo fuses connected to each?

Thanks - looking forward to rigging them up to my mill!
