Hello!

I just joined your forum wich i visit from time to time as i am generaly interested about photography, and mostly about older stuff.
Since today i am happy to own my first brass lens. I did my best to gather any information about but i found nothing...

So, does anyone ever heard about the brand "Simplex". On the one i have, someone can read on the barrel:
SIMPLEX-RAPID-APLANAT Ser. D 13X18. The apperture is f8-44, and a quick test on a white paper indicates a focal lenght of about 280mm (11inch).
No serial number or anything else written. The lens came from Belgium in case that may indicates something.

Just a quick view below (the following images are from the auction as i was too tired after hours or reading about lenses of the period)

From what (if) i understood, my estimation is that this lens must be from around 1890-1900. But i am a total newbee and maybe i am wrong.

I will be very happy if someone may has, and like to share any information about.
