We were in New Hampshire this weekend went to this restaurant for Sunday Brunch and was Seated next to this little Jem .
Cool , dang shame it’s just hanging in a wall . it’s from a duel engine unit . I got something similar in my shed
In the old SW catalogs, most of the panels had a name associated with the sea. The Mate, Navigator, and Ensign. The only one I can remember not marine named was the Hollywood, shown above.
35 Mph speedometer and 3500 rpm tach with the compass over on the side = right out of a diesel powered boat. Pretty damned cool and that was probably originally a pretty nice power boat that had that dash in it in it's day.
Don't leave out the military vehicles, fire trucks, trucks in general, GMC's, Stuebaker Hawks etc. & yes some may have been A.C. logo's.
I have bought the transoms from old boats before, including the dash panel and gauges as well as steering box and wheel. The two I bought had the SW 5-gauge Ensign panels with big logo (1955-58) gauges. The boxes were Gemmer like an F-1 pickup except they had pitmans pointing up instead of down. The steering wheels were like a '40 Ford, except the small ribs were slightly different. The transom even came with cool switches and identification tags which I used in my car ("navigation" for the headlight switch). I didn't find a good use for the throttle levers though.
I see two gauges of everything, tach's included as in dual engines. Hell, there's even two ignition switch's.
That's two 3,500 rpm tachs, for two engines. The speedo would be lower speeds & the graduations would be tighter in the lower speeds than the higher speeds, due to the way the marine speed indicators worked. They had this gizmo called then "pitot" tube, where the pressure of the water flowing into the tube as the boat accelerated was converted into speed increments (mph or knots). At least that's the way the old school boat stuff worked...it's probably some GPS technology these days.
Here's a similar one for you in an old G.M. Diesel panel, https://www.ebay.com/itm/294913031326?hash=item44aa2fbc9e:g:9xIAAOSwsptiUHsN
