The rule is extremely similar to the Post Universal 1452 & Hughes Owens /
Geotec Universal 341 3215, with the inchscale on the bevelled edge and the
"c" guagemark near 1.3. However the rule in the film doesn't have any
writing visible above the A scale, and the pictures I've seen of these rules
do.

Is that the normal way to hold a slide rule? The operator moves the slide
with the ball of his thumb applied near the middle of the rule. (I move it
with my finger tips near the ends, but now I realise I don't know how it's
supposed to be done!)

Hi Guys

I have just taken a digital snap close up of a sliderule in the film.
Anyone want to look at it? Just e-mail me and I'll send the picture. It
has six
scales, A/B CI C/D K and a simple metal and one-line glass cursor. Any
suggestions into the model?

best wishes
