Re: Difference of BOSS Machines
The first thing to understand is that the picture that you call "others" is a Bridgeport Series I machine, while the other machines are Bridgeport Series II machines. You are comparing apples to oranges. The Series II machine has a completely different table and ways than a Series I. I have examples of both machines. The picture you call "current" appears to have a custom way cover for the X axis. I believe the factory supplied the style pictured in the one you call "mine". The hanging way cover is standard on the Y axis of Series II machines. It looks as though somebody added a similar cover on the X axis.
You may be able to find some covers on eBay or Craig's list if you keep your eye out.
