1948 Studebaker gauge cluster & 50's Corvette valve covers

1948 Studebaker Dash Gauge Cluster.  Die-Cast metal & is incredibly heavy (!)  The holes are slightly over 5 inches in diameter, which is very large for a gauge... (the larger Porsche 911 gauges are about 4.75 inches)


Picture (from the net) showing a similar cluster in a vehicle.  I don't know if the grilles are for HVAC or a speaker (guessing speaker)...
This broken/degraded clock was in the middle space on the gauge cluster.  It must have been sitting outside for a long time...


Corvette small block chevy valve covers.  May be originals from the 50's (have a casting #, part #, and manufacturer's logo on the inside).
