Overall very good condition, great piece for collection and demo how calculation was performed (not the logic as today). Comes with reprint of original manual in Bulgarian language, but formulas and way of calculation is understandable. Can be translated by online translators. Missing original product tag with serial number, but according to chassis and electronics suppose to be produced probably in 1972 or very early 1973. Next generation (1973) have smaller, white nixies.
Why stated 22M if there is 22 on the label? All Elka 22 till serial 63 000 are with metal base and reversed boards. Every board have sequence letter - A, B, C, etc. REMARK - Calculator is working, checked and repaired.
