You can use this one as reference.

I just sent it out yesterday. Not in my hand anymore. Mauser finish could be confusing. But this one can be used as a reference.
Hammer is supposed to be grey. Trigger finish depends on s/n. Rough rule of thumb -- if it has 4 rifling lines, strawed trigger. 6 rifling lines, fire blued trigger.
