Hello everyone,

I have one old lens written on it the inscription R.O.J.A vorm. Emil Busch Rathenow. Portrat Doppel-Objectiv n°2 Foc.21 cm
Can anybody tell me how old and the estimated value ?
Thanks in advance
Jp

I believe the lens dates back to 1860-80's and it's worth only what someone is willing to pay. Could check E-Bay for similar sold items.

Here is a bit of info...... Emil Busch
