The screw was a brass screw that held a sliding piece of
metal that you slide up and down to put the lens board
in. Then you tighten the screw down.
Just the head was stripped, and not the actual threads I
think.
I didn't see how the camera repair guy fixed it, but he
did it pretty quick, in the back. He's a genius.
For people in TX: It's Mike at Professional Camera Repair
on Richmond in Houston. He's an Indian guy and he does
really good work.

This sort of mounting is provided a many cameras.
Usually the lock strip is a spring which is dished slightly
toward the lensboard at the center. The screws holding it in
place are shoulder screws that do not go in all the way but
leave enough clearance so that the strip can be slide over
to remove the lens board. The spring action both hods the
board in place and keeps the strip in place until you push
it over.
There are two (at least) types of wood screws with
round heads: one is threaded right to the head, the other
has a small un-threaded shoulder. The second is the kind you
want. Old fashioned hardware stores usually have these
screws but you might have to go to a hobby shop to find
them.
In any case you should not have to tighten the screws
to hold the lens board in place.
Where wood screws have enlarged the hole they go in too
much the damage can be repaired by drilling out the damaged
wood and gluing in a hardwood peg. The peg material is
avaiable in hardware and hobby shops. Once the glue has set
the end of the peg is sanded even with the surface its in
and a pilot hole drilled in it with a small drill so that
the screw does not split it. Since the end of the peg would
be hidden in this application no refinishing is necessary.
