I use an Ilex #4 with my 19" red dot. Make sure to purchase a shutter tester and calibrate the shutter. You should calibrate every shutter you use especially when shooting 12x20 with the cost of film. I put pencil marks on the shutter dial for the speeds e.g. 1, 1/2, 1/4, 1/8, etc. All Ilex shutters vary in actual speed from the markings on the dial regardless of when they have last been CLAed. A good service technician will give you a calibration sheet when a shutter is CLAed, but Ilex shutters may vary with use or age. You should always fire an Ilex shutter a couple of times at the desired speed before exposure to get the most accurate exposure. Copal shutters are more accurate but are much more expensive. Pay someone to do the mounting. Other posts here mention a couple of options.

speaking as someone who has written ad copy for the last quarter century, while S.K.

The Grimes folks mounted my 19" Artar into a Copal 3 shutter.
It is ever so much more elegant to be able to set the iris on f64, open the shutter and count off the seconds... then close the shutter.
More elegant by far, than it was to slip my lens sock shutter over the barrel mounted Artar, set the iris diaphragm to f64, slip off the sock shutter and count off the seconds, then slip my lens sock shutter back over the barrel mounted Artar.
Can't see any difference in the negatives, But...
Thanks for all the replies. Ok, I'm thinking of bidding on a packard shutter on ebay. It is a 4 inch shutter with a 2 inch opening. Here's the thing though: I don't really know anything about these shutters at all. How do they work? How are they mounted? What are the speeds?
Any insight/advice is appreciated.
