Hey,
I agree with paint job and rusty... very cool man!
But I have little critics on model:
1º Red line: See this line, is more angular, like a Blue line.
2º Green line: This cut finish in in the rim arch.
See the link on Ebay. Having many pics of reference to help you to got a more accurate model.
