Guedon Plastic-Pocket

• Type: Closed Body Mannheim
• Size: 6 Inches / 16 cm
• Material: Plastic
• Scales:
• Front: A [ B C ] D
• HvH variant of 3575

With sewn leather case. Inch scale on the front, centimeters on the reverse. No trig scales on reverse of slide. Obverse scales are unlabelled. An advertising specialty item. Rumor is that Guedon was able to make these for 50 cents per unit in an attempt to undercut other manufacturers. Quality will tell, however. The material feels like the sort of celluloid that photographic film is made from.
