A while ago I bought this bronze plaque on a Dutch auction site, and I wonder if anyone has seen this before, knows where it came from, how old it is and what it was used for? Probably a sign for Marine workshops, or a ship's engine-bay?
The plaque is made of bronze, app. 25,5x17,5 cms (10"x7") and 5mm thick (1,8").
I seems that is was never used, it shows little signs of wear.
Could it be a replica from an original, NOS, or even a plaque made for curios?In the last case, why would someone bother to make a plaque for marine engines in stead of well known cars?
That's a beatiful sign! Alfa Romeo made marine versions of the straight-8 found in the Tipo 158 and 159 Alfetta in the late 30's/early 40's. They were fitted to a few racing boats from Ezio Selva, Mario Verga and Achille Castoldi and raced on Lake Como and Lake Garda. Selva is still producing outboard engines.
Apparently one of these record-setting boats are preserved in Museo della Barca Lariana on Lake Como, unfortunately sans engine. Maybe the plaque comes from one of these?
On the other hand Alfa also made marine versions of their engines earlier than this, so the plaque could be even older. That's unfortunately all I have
Certainly not custom, nor as rare as marinized-158. Alfa produced for many years, starting during the war and well into the 50s a marine version of the Diesel straight-6 from the T800 truck, called AR318. At a certain point, it changed moniker according to a version update, but I need to dig in archive from finding it back. It even powered some Venice "vaporettos", among others, as documented in the book "Alfa Romeo Immagini".
