Canon IVsb Shutter speeds OK, dial off

[Derek Leath]

Hello all.

I came across a IVsb and the shutter speeds seem fine, but the dial is off by two places.
500 is bulb 1000 is 25.
If I take the dial off, would I be able to re-align?

thanks

Yes the dial is adjustable. Just cock your shutter, loosen the set screw(s) on the shutter speed dial and turn to the correct speed you think it should be.

Possibly originally caused by adjusting the shutter speed without first cocking the shutter?????? I think I had something of this sort happen to me due to my absent mindedness on one occasion.

Seems to fine now, I just cocked The shutter a few times. Thanks all

1/1000th sec Dial a little higher than the rest.

My IVsb shutter dial sits (or clicks into every place), but on 1000 it sits a bit higher. still works, but wondering if it should click into the slot?

Thanks

No, the shutter speed dial should rest a bit higher when set to 1/1000. Many old 35mm rangefinders with a horizontal focal plane shutter are like this (don't ask me why).
