The paint is Dunkelgelb - a commonly used paint color later in the war and not necessarily associated with Afrikakorps. You can probably determine the year of manufacture by the serial number. They appear to be military grade since they do not have center focus adjustment. Does it have a reticle in one eyepiece? NH
The only number I can find is 479...and yes the reticle is present in the right side.
Thanks for the response
