Kevin's Watch

"The Arithma Addiator is one
of the earlier calculators. Using the
the pen-like brass stick that you can
see clipped to its left side, the user
would perform calculations by inserting
the tapered end into the slots next to
the numbers. The top set of numbers
would be used for addition, and the
bottom for subtraction, with the total
displayed in the center frame. This
calculator was in production in 1962,
and was relatively cheap, normally
costing under five dollars."

still has the original stick, case and instructions.

from that site...

To the best of my knowledge, DeJur
didn't actually make anything, they were
an importer / distributor of items branded
under their own name. They were most
well known in the 40s and 50s for amateur
movie equipment, but they dabbled in other
things like enlargers, meters, and the
occasional still camera. In the 60s the
company went into office photocopiers,
and sold out in 1974 when the owners,
Harry and Ralph DeJur, retired.

This appears to be a domestically
made Hickok. It's very close to my
Photrix SS and to a lesser extent
my Duplex. They're about the same
size and weight. The meter is inside
the dial, and on both this and the
Photrix, you have to turn the glass
itself so that the pointer lines up
with the exposure index, and then
turn the dial ring so that the pointer
lines up with the hash mark that the
meter needle is pointing to.

The ad linked here is for a Model
40 "Critic," but it's the same meter.
The difference is that the Model 40
was calibrated in Weston numbers
and this Model 50 uses ASA. DeJur
did the same thing with their simple
Model 5 meter: the A version is
Weston, the B is in ASA.

Cool! Reminds me of a slide rule, except the slide rule, uh, slid. And it could do more complex stuff than just add and subtrack.

That's cool, I like it.

That's cool, I like it.

In fact, so cool, I like it twice

We've got ghosts in the machine again, I think. I've been cleaning up double-posts in here a fair amount today.

ali - well it is the first of it's kind. so not a lot of bells and whistles.

phantasm - so do you like it?

not sure the meter works - mostly because i'm not sure how it's supposed to work.

If he liked it any more, you'd have to use it to calculate how much he liked it.

dAn -




we are hoping next week to talk the shop
down on price for that can. and they have
dice that do not have the numbers stamped
on all sides - i will be picking some of those
up for an art project.

went to our first ever auction last
Saturday near Spring, Texas.

thought it would be too much $$$
to paticipate but we got lots of
cool stuff real cheap.

for $5.00 we got the following...
six small gold Buddhas. one box
of mixed books with three real
winners (1976 copy of the Eastern
Star Rituals, with a first page
dedication dated 1977. Engineering
Drawing book 1953. and tucked into
that a book of Mensuration 1941)

a set of nice dishes for julie. an
abstract painting done in acrylic
for my art room.

and for @$20.00 a pair of great
lamps for our bedroom.

we had a blast and hope to go
back as soon as we can afford it.

the Philco I bought.

What a beautiful radio! I used to know folks who collected old radios. What are the preset stations (the call letters) on the dial?

can not read the number.

also i have some confusion as the numbers don't seem to add up. but i found a philco forum so i should be able to get some answers.
