Franco-Prussian War/ WW1 German Bronze Guardian Angel Plaque

A most appealing and possibly unique bronze plaque depicting a winged guardian angel comforting and supporting a wounded, possibly dying German soldier.
Difficult to put an exact age to this wonderful work of art, unsure if WW1 period or much earlier, observing the equipment/pouches worn by the soldier it appears to be more Franco-Prussian war period (1870-71) or simply just down to the artist/sculptor working from pre-WW1 images.
This heavy bronze plaque in raised relief measures 32cm x 25cm and does bear a miniscule artists/foundry mark to the bottom right corner, have not yet identified this mark after much research, the rear has a central threaded type fixing with hanging ring, there appears to be a crude modern day repair to the fixing as dare say the thread has been stripped over time, remains firm.
When tapping the plaque with your finger you can instantly tell the bronze is high quality as it rings like a bell, please note that the photo's were taken outside in natural light as the patina is much darker undercover/inside.
Many hours have been spent researching this piece and I have not found another online or in any reference books nor anything similar.
Sorry UK sale only.
