Hoping for some help.  My mini engine has just come back from Minimine (thoroughly recommend by the way!!) and while cleaning up the head a 'CH' stamp was found on it.  It's clearly an aftermarket stamp and I can see the head was already modified by someone.  Anyone know of a machine shop or mini engine specialist that might go by the initials CH?

 

Thanks,

 

James

It could be that the rest of the digits are missing and the CH is for the chamber volume but most just punch in 21,5 for instance.

Pictures. 
 

they tend to work better than words.

 

location and type face mean more than the letters.
