Although still early on in my shutter repair studies and service, I can pretty well tell you that you do not have anything near any kind of accuracy going on there. If you have not made yourself up a little home made shutter tester to see where you stand, then any use of the camera as-is would be a waste of time and film. At best, you'll be torturing yourself making test strips in the darkroom before every print. That 200 speed is probably more near 1/75-1/130th, and 1/100 is probably more like 1/60. Somebody is going to have to get the shutter apart for a cleaning and a look-see for wear. As it is right now I'd venture to say 1/50 is the only speed on the camera that's in the ballpark.
