Not all numbers painted on parts were actual W.Nr, lots of component numbers found on components at service center in France. Never heard of any Cheb production.
Only those already posted.
"770003" might be 0177 0003 (not six digit secret code) but V3 / 0003
no ""77xxxx" series in my list, but its not that much of a list.
Nothing to write home about.
