This is an interesting MB 41 C Ford GT.
My guess would be that being regular wheeled and yellow it is from the G-4 Race Track Set.
Take a closer look ( although the photo doesn't do it justice ) and this model looks like it was white and then over painted yellow !
This is telling me that there wasn't enough yellow paint Ford GT's for the gift sets and some white ones were over painted. This model could therefore be from either end of
the gift sets life span. It could have been a trial model for the gift set to start with or at the other end of the spectrum with the superfast models coming on line the white
regular wheeled models needed using up.
What do you think ?
