Help with identifying the brand of a vintage bike I've been trying to find out about the provenance of a vintage bike.

It is fitted with:


a USA Sturmey Archer 4 speed FW.63
Wagner Werdermann front hub
The brakes are Weinmann.
Cranks are Williams.


The wheel chain is either a triangle or a pine tree.

On the frame, there is a double ram horns

Wheels are 27x 1 1/4 or 32-630

And on the fork, there is a light bracket.

The plaque has been removed.
No markings anywhere visible.

It seems to be hand painted.

It looks better than in the pics.

Thank you for your help!
I might have found its provenance from the net.
