Kemtron Corporation was founded and owned by Kemalyan. :Kemalyan started Kemtron in Fresno in the early '50s (possibly even 1948 or 1949), and he provided layout space for the Fresno Model Railroad club in the early '50s. In 1960, the Kemtron plant was with 15 employees. One of Kemtron's product lines, photo engraved car kits, particularly the flats, often used zinc (or a very high zinc content brass) sheet, as opposed to brass. The 'blue' coating, was the 'photo resist' that was not cleaned off. Kemtron was initially a sideline of Fresno Photo Engraving, which explains why common photo engraving materials were often used. In the mid-1960s Kemtron also produced a line of slot cars and accessories.
