Hey, I'm not cheap! I'm thrifty. But thanks, anyway.
I discovered this by opening it to put in a new roll, so the 1st 3 shots are ruined. A check of the shutter and aperture settings suggests it's either PANF or FP4. So, I'll just shoot remaining 9 at 100. That's a good idea about stuffing the box end into the accessory shoe, if your camera has one. This Compur shutter doesn't even have a flash sync.
Thanks to all.
