Anybody associated with D-FYAK?

I am looking for someone who is associated with Yak-11 D-FYAK or possibly knows the owner and can forward a message for me. I am building a flying model of the Yak and am looking for a suitable paint scheme to reproduce. My first intention was to duplicate an in-service example but finding color information has proven to be very difficult. In order to compete with this airplane, as is my intention, I need proof of color documentation. That means color chips, reference numbers from the paint manufacturer, or something else that verifies that the colors on the model are accurate to those on the prototype being duplicated. Therefore, I would like to get in contact with either the owner or possibly the shop that did the paint work on D-FYAK and see if the information is available. I am happy to respect the privacy of the airplane’s owner and am not asking for his contact information, only for somebody that may be able to forward my request and my contact information to him. Any and all help much appreciated.

PS – I’m in the USA and only speak English.
