All metal construction.

Serial No. 1763296 - therefore made in 1933.

No fungus or internal dust visible.

Focus smooth and aperture clicks nicely, no oil on blades etc.

A couple of small streaks / scratches off centre on front element.

Can't tell if they're just coating marks. (please see pics).

Not noticeable when used on a camera however :)
