I won this BK-100 on eBay:http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3049037452
It seems to work well and feel good (smooth and no slop), but I'm kinda concerned...in doing a teardown and cleaning last night (looked like a smoker once owned it) I discovered there are no bearings (ball, needle, etc.) in the lower pivot cup. Should there be and if so, what type and size?? If someone has a pic of what it should look like, I'd be very appreciative.
On mine, all that I have are two jeweled pivots on the lever arm that fit into receiving cups--much like the bearing system on an old J-38 straight key.
