Occasionally I get all altruistic and let people have free stuff such as the plans below, for models I've previously built. They are JPG files but I also have the plans available as PDF files, simply print them out and use them as a template. They have been drawn to fit on to an A3 sheet to suit 28mm figures.
If you have any problems send me an email and I'll forward you a copy of the files.
If you do make a model based on the drawings please let me know, I'd love to see the results.
