Ilex #4 Universal shutter question

[M Carter]

Take a look at this Ilex shutter - there's a dot with each shutter speed to align the rim set mark with... but the 1/100th speed has an additional dot on each side. Anyone know what those dots are for?? No luck searching the web for a manual...

Yes.

Yes.

But seriously, I have seen one other Universal marked like this on ebay (maybe this very shutter). I would guess something custom, maybe for high speed calibration or additional speed increments.
You might email Carol at Flutot's shutter repair.

Yes.

:-D

I don't know, but at a guess might they be 75 and 125, but unmarked ?

Do the extra dots have detents?

Nope, none of the speeds have detents, it's "align and fire". Oddly, now that I've mounted it on a board, the speed selection is really, really stuff, will have so suss that out.

What type board, wood or metal? Did you use a flange on front of the board or retaining ring on back?

It may need a spacer between the board and the back of the shutter to prevent the aperture lever from binding on the board.
