I believe that's a Foch Wolf, not a Messerschmidt...
Definitely not an FW-190. That pic is an ME-109 (actually Bf-109) variant.
See .44 Special's post #16 for what is almost certainly the correct answer.
Here's a good pic of a Bf-109:

The yellow-nosed aircraft in the link below is actually an HA-1112, though painted in German markings.

...nope...the FW-190 had a BMW radial engine,and a distinctive hole in the prop cowling which was the opening for a 20mm cannon
