Looking for a copy of a Remington Mohawk 48 owners manual/parts schematic.....

You could try Remington:

Remington's Consumer Services Department at 1-800-243-9700

or

You can also request an owners manual at 1-800-243-9700

Pedestal:
Same gun as the 11-48 or Sportsman 48 I believe. Go to http://www.e-gunparts.com/productschem.asp?chrMasterModel=0860z1148 and you can print out a schematic for this gun.
Hope this helps.

Trapper:
Thanks! If they are the same thing the schematic told me what I needed to know...
