After reading my web-pages Mr. Hy Schwartz, one of the founders of
the Kalart company,
sent me an email in which he offered to share photos of his old
manufacturing location to publish on my website.
Furthermore the original concept and test print of their Kalart
Rangefinder Instruction book with his handwritten corrections.
That was back in 2006 when he had reached the respectable age of
103 years.
A very remarkable man!
