These 38 HP* case gauges are overruns for a special group that was so far under the radar we think they might not even exist.  So, once they're gone, they're gone.  We're talking chicken teeth here.  If you don't know what the .38 HP* is, you don't need this and please don't ask because we won't tell you.
