This is an extremely clean Big Shot from my personal collection It has been tested and works flawlessly. The shutter is crisp, s’more, s’more this one has a great shutter. When I still had a commercial studio I had a shelf full of them. It has the best shutter of any I have ever had. The shutter and aperture work correctly the flash housing rotates. there is zero residue on the rollers. I ship the day I receive payment.
