General parade-walking out uniform

[Esteban_cool]

Gentlemen,

I have finally acquired a general´s tunic. Now, there are some things that I´d like to know.
First, as you can see the bullion leaves and stars have become very very dark. Is there any chance to restore their shine with something?
Second, there is no embroidery on the cuffs. Is this because of the manufacturing period?
Third. It seems this general had almost no action at all or the ribbon bar is not original to the tunic(altough he was awarded the Sino-soviet friendship medal and the cloth backing matches the tunic´s). Assuming the first, any ideas of his work? Maybe as an advisor duirng the last years of friendship between both countries?

Thanks,
Esteban
