The panel isn't homemade. There was a company selling them which I don't believe is in business any more. They had 2 or 3 different finishes on them of which one was the engine turned finish. I have one that I never used.To me the panel looks like it's homemade and as far as the gages go they look like something cheap to fill the panel.
THanks for the links,, Those Eddie motorsports and west Marine ones are almost identical....Looks like a set that is sold under many different brand names, and then priced accordingly. See how similar these look:
Elite 6 Gauge Kit with GPS Speedo, Universal Fuel Level Gauge White (eddiemotorsports.com)
Classic Dash 61264WP11 (summitracing.com)
White Premier Pro 6 Gauge Set | West Marine
Oh yeah, looks just like it...I have a similar dash bezel from River City Muscle Cars.https://rivercitymusclecars.com/
