They seem to be in the $325 to $400+ ballpark....they have always been HARD to find clean and like it`s "Father" the f1.5 50mm Xenon - they almost ALWAYS have the cleaning marks and haze/fogging issues
I did have a rare 1949/50 Taylor Hobson issue one back in Germany in the 1990`s and I remember back then I paid like nearly $450 for it with a bubble case, front cap, shade and rare UV filter
(that was back in my nutty collector days when I had like 25+ cameras in the house - funny but I DON`T miss it)
They are a interesting lens, built well, but "softer" signature, then say for example a Nikkor f1.4 50mm etc.
If razorsharpness is your "thing" this lens is NOT for you - hummmmm finding a "beater" Summarit will be honestly EASIER to do if you buy a WHOLE camera.....look for a used up IIIF BD on the Evilbay perhaps that`s the BEST way to get one of those - most really clean ones are SCOOPED UP by the collector sharpies out there....
Good Luck!
