Thanks very much Joel and Brian!
Joel,
The camouflage scheme I used on this model was the last one used on the Bf 109K-4. The upper surfaces were painted in RLM 81 and RLM 82, the fuselage had these same colors softly sprayed on the top and upper sides while the lower half of the fuselage was unpainted. About midway on the side of the fuselage a thick wavy line of RLM 76 was sprayed on blending in the paint with the unpainted parts of the fuselage.
Here are some photographs of some captured Bf 109K-4 fuselages that were painted in the scheme described above. If the war had dragged on a little longer this scheme would have been in widespread use.

Brian,
From bits and pieces of information I have gathered here is the short story behind the four bladed propeller on the K-4.
First of all the Bf 109K-4 was never designed to use a four blade propeller, the last 109 version that was planned for production was the Bf 109K-14, the K-14 was to use the DB 605L as its power plant and the DB 605L was designed to be used with the VDM 9-12199 four bladed propeller. Some work was done in preparation for the upcoming K-14 production but before that could take place the RLM decided to stop Bf 109 production with the K-4 version and drop the K-14 in favor of producing more Ta 152's. Months later because of interruption in the supply of power plants for the K-4 permission was granted to go ahead and use some of the DB 605L engines and other components that were intended to be used in the K-14's in order to keep the production line for the K-4 moving.
There have been stories over the years that some Bf 109K-14's were actually used by JG 52 in the spring of 1945 but in reality that was just people mistaking the Bf 109K-4's with four bladed propellers as full blown K-14s.
Here is another picture of my model.
