Front element filter size on Kodak Portrait 305mm F4.8 lens?

[LFLarry]

I am traveling for the next couple of weeks and don't have physical access to my Kodak Portrait 305mm F4.8 lens.

Anyone here know what size filter it takes?

This brings up another issue as well. I am not clear how to determine the size of a filter based on its measurement. Any help here is appreciated.

Thanks in advance.

Measure the outside diameter of your lens to determine which adapter will fit best. Unfortunately I don’t have one to measure.
