M Muller Rechenschieber enquiry

[Steelmillal]

Hey all, can anyone comment on Muller Rechenschieber? Short story is they are circular slide rules, or linear scales (computers), that match Muller equations. Input this, output that. Q.E.D done and sorted.

I've only seen photos in old journals before receiving a men's and women's, and I've yet to find other images online. I'll post photos soon. Thx loads, y'all.












Photos added. I've only handled these twice. They were in a lot I bought recently. There's one larger and three small books, including a copy of the following:

A friend is looking at the rest but if she punts, I told the seller I'd mention it all here. The grading books are left, and 17th "Damen Kostume Zuschnitt", a "Blusen", and some catalogs from the 50s. Rare stuff for the States.

It consists of 3 round metal discs of different sizes - all revolving around a center. Scales were engraved on it. If you then set the chest, waist and hips (rotating the disks), you got the calculated value for the construction of your pattern.

I believe I have an old one for women's measurements packed away somewhere.

Now I want to find where mine is! When I bought it years ago I also couldn't find any other photos online. My one is made from heavy card. I'm curious if they are the same.
