Someone gave me an old enlarger. It has no markings on it, but it came
with a set of Paterson trays, Paterson tongs and a Paterson 3 element
lens, so I'm guessing it is a Paterson enlarger.

I have no data on it's age, but it came with a bulk loader still contaning
film with the flap from a roll of Tri-X with a 1990 expiration date.

It consists of a plastic base, a metal pole that screws into a threaded
cap which fits into the base and the enlarger itself. The enlarger has a
push botton on the bottom of the arm to relase a clamp against the pole,
a red knob to slide a red filter in and out and the a hidden push botton
which allows the entire top of the enlarger to pivoit backwards allowing
you to move a negative in the carrier.

There is a metal housing for a regular size enlarging bulb which locks
in place with a twist. The condenser at the bottom of it has a frosted
flat side, which can be moved by twisting to hold the negative in the
carrier.

It came with 35mm and 126 carriers. The lens has a regular leica thread,
and screws into a larger threaded ring for focusing. There is wire bail
that looks like it holds up strips of negatives if they are in the carrier.
This took a while for me to figure out, it rotates but seemed to have
no function. At first I thought it was the release for a missing top
of the negative carrier, but then I figured out the condenser can
be rotated to hold the negative in place.

There was a drawer for filters, but it's missing.

Any information about it would be appreiciated.

Thanks, Geoff.
