Looking for pictures of YAK-18P

I´m looking for pictures of Yak-18P aerobatic aircraft for a small project a friend of mine is working on.
I´ve done the usual search on the net, and all the books I´ve got access to, but it seems that very few Yak-18P photographs are floating around. So far, I´ve found one colour photo of -18P in the book Flight Fantastic, and that one is widely circulated on the net. That photo is of machine coded #30 and is taken at the World Championships in Bilbao. The only other photo I´ve been able to find is a B/W photo of a machine coded #43.

Photographs of the later Yak-18PM and -18PS seem to be more numerous for some reason. Strange, since they were only produced in about 20+/- examples each, but there were at least 125 Yak-18P produced.

If anyone can come up with more photos, particulary of a machine coded #33, I´ll be very grateful.
