Heliostar

This article is a stub. You can help Camera-wiki.org by expanding it.

The lens name Heliostar is found on various Japanese cameras of the late 1920s and early 1930s. The full engraving is Heliostar Anastigmat München and is easily mistaken for Hellostar. The maker's name is not indicated, and the exact origin of this lens is unknown.

Example observed in an online auction on a CH enlarger. The example pictured in this page at Takasaki Motohiro's website certainly adapts on an enlarger too.
