We had a Zeiss 40x/1.3 Oil that we found to be similarly stuck. There was a small dent on the metal surface near the front lens that suggested the someone had hit the lens against the stage (or other) as suggested by Eric. It turned out I was able to remove the little screw on the side of the objective barrel, and by holding the objective up and pressing down quite hard on the front I was able to unstuck it. There is a little notch in the inside barrel that needs to be aligned before putting the screw back. I'm guessing that depending on whether the objective got stuck "in" or "out", you may need to apply pressure differently. The good news is that our objective was able to move in and out again, and it looked optically OK.
