My brother-in-law has an Ithaca SKB model 900 that needs a good cleaning. Does anyone know where I can get an owner's manual for the gun? I found manuals for the Model 900 XL, but that's a gas semi, the 900 is a recoil oberated. I've been able to break the whole gun down, but I cant get the bolt out to clean it. Any help is much appreciated.

Thanks,

Frank
