Hi Wendy! This is a 6x7 unit, so: is it a MLU unit or not?. One of my 6x7 MLU bodies did this while in India in 99. In addition, I think you may not have much on the rolls you continued with: when you said "Taking the battery out, the mirror dropped back down and the lens aperture opened' you have yourself a very overexposed frame! Hope you didn't loose anything!
WHAT HAPPENED:The only difference is in how I had to recover: Once the shutter was fired (which locked the mirror), the only way out was to press the recessed Mirror release (about 1" below the shutter on the front side of the camera) and fire the shutter again. WHAT WAS WRONG: I took the body into repair, and was told that the mirror actuating SOLENOID - intenally a big green thing in the panel under the mirror release button - was fubar. I believe this gets stuck in "push the mirror up mode" - when you take the battery out (or push the little button) you take the charge away from it, and it releases the mirror. WHAT I DID : As it cost more to repair (In NYC, $250) than buy on ebay, I took the easy route!
