I have not been able to ID this pressed glass clock, it glows very brightly with a little UV. The quality for a pressed item seems quite high to me (the clear sections I think are polished), no makers marks and I suspect the movement is not original as it does not fit properly.
I have not trawled all the catalogues on glas-musterbuch.de yet but I did check the Heinrich Hoffman catalogue and looked on Pamela's Pressglas-Pavillon. There is something familiar about the 'pillars' topped with flowers flanking the main body...
Any recognise the pattern?
