Want to Buy WTB: inexpensive uncoated lens in barrel to cover 4x5 for experiment

I'm playing around with making some home built cameras for fun. I would like to find an inexpensive uncoated lens in barrel with working aperture to cover approx 4x5 or larger.

I want an uncoated lens because I want to experiment with using cyanotype material for in-camera exposures. Modern coated lenses will filter out much of the necessary UV spectrum needed for cyanotype material.

Would be nice if it came with some type of mounting flange/bracket, but not a deal breaker. An enlarger lens may work (?).

Please PM me rather than post to this thread.

Thanks,
Keith
