I finally got around testing the Lustrar, probably a dialyt type lens from 1921, i.e. 4 elements in 4 groups, which means low contrast due to veiling glare and maybe half a stop losses, similar to a Cooke Aviar.
I've only tested the lens at the full f/4.5 aperture, and it seems to perform reasonably well - for a 9.99 GBP lens. Here are a couple of examples, the contrast has been adjusted:
However, like with the Aviar fully open, the bokeh can be rather distractive, and I must later on test the lens also stopped down. Here is a model example of the bokeh:

nice lens with perfect colors and quite good wide open
#1 is very nice
I like the bokeh on #3 but not the left border of #2 where the cord is fuzzy _________________ T* |

Well, it seems the perceived quality of bokeh is very much a matter of taste That's the kind of bokeh I try to avoid at all costs because in a more complex scene it has an effect like this:
The upper part is Lustrar wide open, the lower part is Aviar wide open. The next pair is Uno f/7.7 wide open and Aviar at f/8, this is what I'm after:
Here there are no bright edge highlights, especially the Aviar is very clean in this respect. I'd like to find a lens which would be sharp but still behave like this also at larger apertures.

I'm fully with you Veijo,
that bottom shots look much better in term of bokeh, the top ones irritates the viewer (me) a bit.
I remember some tests I did some time ago with that lens, a dialyte type, which were nice, but I have to re-examine that first.

Im afraid I like the former bokeh too, as Ive yet to learn to make bokeh anyways. So that figures why I like the lesser proper bokeh... lack of expertise. Bokeh only happens to me by accident. But these bokeh are as oil paintings to me. |

The inexpensive Zeiss Jena Sonnars provide a lot of bokeh quality for the buck
Specular highlights and other out-of-focus bright spots don't tell the whole bokeh story
Bokeh is subjective, but it is not an illusion
