Gamma 1252 zseblogarlécTry It!
A lécek árai (szabott árak miatt) a gyártás folyamán végig azonosak voltak, az I. osztályú léceké 90,50 Ft volt, a II. osztályúaké pedig 60,40 Ft. Az ár egy műbőrből varrt tokot is tartalmazott.
Due to decrease of manufacturing costs the appearance has been modified: all labels and markings printed in black. The GAMMA-BUDAPEST markings were replaced with the Gamma logo. The cases were simplified, box-shaped without any label.
This variation was produced at the Brush Factory in Monor, with brand name "Logar". All rules has markings for classification results.
After publication of the standard MSZ 4617-57 for slide rules the templates used for manufacturing pocket slide rules were re-designed with typeface according to the MSZ-standard. The labels for back scales were changed from S, S&T, T to sin, sin&tg, tg. A new marking stamp is used in the stock declaring the conformity to the MSZ-standard.
