here we have for sale is a RPM gauge for a old classic car, i do not know as to which car it actually came out of !? the needle is free moving, as can easily be seen from the 2 images there isa additional hole in the back 'red arrows' and there is a small amount of light rusty stuff around the body, when i get some spare the 3x car clocks that i have listed with the help of Preloved will be de-rusted a.s.a.p. !!
