Unknown gantry signal

Hello collector friends,
I recently got this gantry signal from an auction in England, in a lot with other Bing Tischbahn.
I have never seen it before, and I have no idea about the maker.



It is hand painted and with welds, no slots/tabs, so early item, possibly pre-tischbahn, but it is the right size for 00?
Any guesses?

Regards,
Manuel

Hi,
Thanks for the input.
The signal is definitely not hand made, bigger than the Bing TT, Distler, etc, and also different from those KBN 24mm...
The round bases also look made with a mould and a press, not available at home in general... but the stairs and overpass could be taken from something else...
I will go on looking for the origins.
Regards,
Manuel

Hi Manuel,

this bridge looks like handmade long time ago, is not original
even it looks very pretty, so I share Claudia´s opinion because…

yellow circle… the ends of the bridge are not symmetric, this
never do a professional manufacture…

red lines…this is one original signal bridge, don´t know the
manufacture…



I suppose somebody cut bridge to save some space on display,
because the original bridge is very wide, the third signal is
missing…

Hope you can read my english and hope you can follow me…

Best regards Georg

Edit.... as you show in first pic this gantry is a one signal gantry,
so my opinion is same, but not as wide as I draw, sorry...
