Let me see if I can help. First its a Mohawk 10c and not c10 and it was made from 1972-1978. It took the place of Remingtons model Nylon 77 which was made from 1970-1972. As far as Schematics go finding them for the 10c will be fun but I can offer you a few options.
First if you want you can go to: http://www.gunbroker.com/Auction/Vie...?Item=28846026
they have your manual for sale for $6.00 or you can go to Remingtons web site log in and ask them for a copy which will take 4-6 wks to recieve
But it will not have schematics in it so if you send me your e-mail, I can try to send some info that way but if not, if you have a way to receive faxes i can fax some info like schematics, disassembly and assembly instructions and visual instruction aids as well that may help although I do not know how well they will send that way either, but anyway if you e-mail me I will tell ya what info I have and you can let me know the best way to get it to you.
