Gunsmithing manuals on auction sites

[35Rem]

Can anyone reccommend a gunsmith, or field service, manual for the Remington Model 11 from one of the sellers on Ebay? They have them for just about anything. Was wondering if anyone here had bought one and was it any good?

I'm looking for something to help me with tearing one down and doing any repairs that may come along. Gunsmiths to work on these things don't exist much, these days, so it may fall to me in the future.

I have seen 3 and they all seem different. Is one better than the other?

Thanks.
