A Dalcoated Dallmeyer 2" (50mm) projection lens in ‘fair-to-good’ condition.
It did have some haze internally but when I cleaned it, it made the Dallcoating a bit blotchy. There are a few very minor threads of fungus towards the rear.
None of this will make any difference to it’s original purpose, and almost certainly won’t make any difference if it was used as a taking lens (remember, as a projection lens, there is no iris).
The dimension of the rear barrel is 25mm (one inch).
