I just found a letter from Lionel Larmanger from POMK from Jan. 7, 1998. He made a 1/48 Dewoitine D.527. As he states it,
"The D. 527 is a plane borned from the mastermaker imagination. The wings are from a P-51B, the fuselage is: front P-51A, rear from D.520. The radiator (under fuselage & wing) is from a Yak 9, propeller is from a P-51A. The radiator is from a Yak 9. The propeller from a P-51A
It's a Franco-American plane with a little Russian. It is a nice kit that should have could fly during the WWII."
I know he sent a three view drawing of it, but was not with letter. Must keep digging. But I hope someone else has the kit and can scan the drawings and post them here. Justo??
