Thanks Greybeard. I haveheard something like this before.

I bought this from a very profilic and respected Ebay seller - a man with lots of lenses and always with VERY long descriptions on what it is....

This time he was wrong. I bought it because I beleved his words that it is a special soft focus lens...
(Fitting this on a board and focussing out side, I got VERY wierd bokeh - like small stars (which makes sense) so maybe it was a "Christmas Card Lens"....))...

So a copy lens it is - I think more from the twenties than the fifties ...

Thanks again
