Default Sterling Dolphin engine

I was looking at a old marine engine in the corner of a shed for a project, I was unable to get a photo as it was too dark to get a decent photo. The model was a CRC or GRC? Any chance anyone knows anything about these? It was a 4 cylinder and one hefty unit. I believe it said it put out 115 or so hp at 1550 RPM. Any info would be appreciated as regular internet searches aren't turning up many things

I have 2 Sterling engines an 8 cylinder Viking an 4 cylinder Dolphin both run an both came out of municipal water plants the Viking was on a generator in South Carolina an the Dolphin was on a pump in Mississippi both have water cooled Exhaust manifolds like a marine engine because they used the water in the water plant for cooling the 8 cylinder has 32 spark plugs 32 valves an 4 updraft carbs 2 distriburters with 18 wires coming from each 16 plug wires an 2 coil wires on each the Dolphin has 12 plugs 3 distriburters an 3 coils it is a 1928 150 HP the Viking is 1938 I have all the literature that came with engine an also a book promoting Sterling that list all the engines they had sold up to 1938 with serial numbers an locations so if you can get serial an model I can probably tell you who engine was originally sold to dont see many Sterling engines

Thanks! I'll try and get the serial number to you ASAP. How good of a runner is the Dolphin? I have no experience with marine equipment

The only ID number I could find on the tag was 031 and I believe it is a GRC 4 model?

Thank you so much! Hopefully we can get it out and maybe puttering away. It's come a long ways since it resides in Minnesota now.
