Excellent shutters for Pinholes!

I thought I'd pass this on: I've built a pinhole
shutter around the Graflex "Speed-I-O-Scope" shutter.
I know that a lot of pinholes are just affixed to a
box & then covered with black tape, which is removed
for the exposure. I wanted to cheat a bit and use my
4x5 & not have to resort to the tape shutter, so I
modified the Speed-I-O-Scope to work. Here is a page
with my modifications:

I mention this because I just noticed a couple of
these shutters available on eBay:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1368084495
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1368083720

The Speed-I-O-Scope is just an Ilex Universal #3
shutter without the f-stops on the face. I know that
any shutter that has a "T" or "B" setting can be used
for this, but this shutter seems to come up often
enough & it is usually inexpensive.

I don't have any relationship to the seller... I just
think these things are usefull.
