I still have this ruler, and I still hadn't ID'd it (last posted in September 20
07)

In a moment of boredom, I googled "18 3/4" and this time...
I got a hit!

In short, it's what we all knew it was  - it's a proportionating ruler,
for working in a clothes cutting system designed by one
Louis Devere.

Based on an "ideal" man, you simply created a pattern in inches,
and for a larger or smaller man, you used a slightly large
or smaller ruler, always working in the numbers from
the ideal pattern.

The "unity" measurement was an 18 3/4 Breast measurement, hence all
the 'B's on the captions, and the fact the 18 3/4 scale is in inches.

Further wanderings in google books (an excellent source of older information)
revealed advertisements for rulers made to this system.

After an interval of 3 years, I doubt this post will thread correctly in the arc
hive :-(

Huh! Hey! What?

(rubbing eyes waking up....)

Did John call up a cigar distribution? Count me IN.

Add the obligatory glass of old Port and I'm all set at this end of the
Porch.

Cheers, ed

Give this man  a cigar for persistence above and beyond the call of

And for rediscovery of a quite an ingenious tool, to boot.
