I need a couple parts for a Bowser Red Sentry curb pump... at least I believe it's a Red Sentry even though all the pictures I've seen so far show a swinging hinged door and mine has a sliding shell. Am I correct that this is just a "model year variation"? Right now I'm looking for parts such as a light bonnet, a fresh "clock face" pointer and dial, though may need help with other part later on. Any suggestions or offers?
