Many thanks for your comments...
The colors look still abit too clean to me, especially the mast, which is really bright yellow...
On the other hand, I know that when the Welder will be weathered, the colors will be more subdued than they are now.
Do you know where i can buy one ready made, as i have just done a rather bad thing and broke my grandads fourty year old modle and would like to do the least i can anf replace it for him.
