I'm replacing the Bottom Bracket on a 1991 Bridgestone MB-3 and it looks like the bottom bracket pre-dates most of the tools I have.
Here are a a couple of pictures that I took.
On the drive train side, it's hard to see in the picture, but there are 2 flat surfaces on the BB that look like a large crescent wrench would fit. I quickly measured it to be about 38mms.

I took the non-dt side lockring off and then came across these holes that I guess you could fit a spanner into? Seems like it's going to need a lot of force to get this off, but maybe a spanner would work.

Looking on Sheldon Brown's site, it sounds like these are cup and ball bearings. I bought a replacement BB already that is a cartridge. Will that fit here (assuming it's the same size, etc) or do I need to stick with the cup and cone?
Any advice on getting these off would be appreciated, thanks!
