P3D slip-in mounts

[Ralph Johnston/Linda Sherman <copley@xxxxxxxxxxxxxxx>]

I had 6 rolls of realist slides done by Sunset last June.  The mounts are
"Pegco".  A few of them tended to slip out during projection because they are
then mounted upside down and the film chips can fall out.  I remounted the best
ones in RBT mounts, then reused the Pegco's for a roll done with a Kindar
camera.  Again a few fell out during projection so I turned them around so the
slits were facing up.  And one of those STILL fell out.  Very embarrasing as it
happened during a Stereo NewEngland members slide show.  I presented a few
slides of the same scene taken with a Kindar and with an RBT, both with 35mm
focal length lenses.    The difference was dramatic as 5perf widened to 8perf
and filled the screen.

John McDonough did a slide mounting workshop at the meeting showing an
interested group how he does heat-seal mounting.
