|Need help identifying older AM Classic BB||win2ktta|

|I have an older AMerican Classic BB on a bike I got from ebay last year. The componenets are 8spd STI Dura Ace. I am replacing my frame, so this is the first time I have had it off the bike.
After I got it off, I noticed that it had sealed bearings but also a bit of rust on the inside (between the cone and the bearing housing) I cleaned it off and it seems to be in pretty good shape. I will say that it is smooth and has been working without any problems since I bought the bike it was on last year.
I am wondering though just what I have and if it is serviceable. I know nothing about it except that it is an American Classic 68mm with a 1.37x24 TPI. I would like more info so I can evaluate if I can/should serivce it and how to do it. I have an image at http://www.ntsinc.com/amcbb.jpg, any details would be appreciated. With all that said, I have a couple of questions:
1. Can anyone tel me how old it is or the model number, etc?
2. Is it worth maintaining? (i.e., should I get new lock rings to replece the ones I scarred, etc.)
3. Can/should the selaed bearings be replaced? With what? How often? Where would I get the replacements? How much are they? Is it worth it?
4. Can/should I ever lube it? If so what do I lube? Do I have to use a special lube or will a general head set type lube work?
I do appreciate any info.

|Howdy, Yes, it is an American Classic bottom bracket. Is it worth servicing, ABSOLUTELY! You have a completely servicable bb there. We have all the parts to make that 100% new. Age wise, it is probly late 80's early 90's. We haven't used those cups in quite awhile. We use ones now that use a specific tool made by us. You should replace the bearings and lockrings. The lockrings are 6 usd each and the bearings are 10 usd each. And you would be all set. You can get replacements directly from us, or you can have your local bike shop order them for you. You should lube or atleast check your bb once a year. As for the type of lube, We use and recommend Finish Line Teflon Grease or Pedro's Syn Grease. They both work wonderfully. If you have any questions or would like to get parts give us a ring.

|Breat to hear it can be serviced. I looked at the web site and cannot see where to order the individual parts. Can you give me a bit more on the specifics so I can get them.
