PIC Electro

Back

Slider Back

This rule does not bear the manufacturer's name. However, I am assuming it was made by PIC, because of double beveled structure.

Since it is difficult to see the scale names from the scans, I will list the scale configuration below.

Front: 10inch/ S, A =B, Dynamo-Motor, Volt, C= D, T\ 25cm
Slider Back: LOGLOG, L, F (F is the normal K scale.)

This rule has a few very unique features over regular "Elektro" rules.

1. LOGLOG scale is on the slider back and trig scales are on front for this rule. The placement is reversed from the normal Elektro rules. Further, the LOGLOG scale is referenced to A scale, thereby enabling to cover the range of two normal LL scales with a single scale.
2. To reverse the slider, you reverse it horizontally for this rule. After experimentation, this makes sense. You pull out the slider and, with a flip of your wrist, can insert the slider without changing the hold.
3. The centimeter graduations at the lower bevel are annotated from right to left. And numbers are upside down. Again, this makes sense because you would rotate the rule and put bottom side up when you want to measure something in cm.
