Heavy solid brass fish head and tail - ends for a sign board or a tray?
These need a little creative repurposing to supply a 'body' for a fish!
We'd guess these pieces are probably 1980s vintage, Arthur Court style. They don't appear to be marked that I could see.
The fish head (just the head) measures about 4 1/2" from the nose back, 5 1/2" top to bottom.
