Tom, many thanks for these two pictures, this is exactly the sort of pics I needed! What is the source if I may ask?
Another interesting fact is that the writer (Simpson?) mentions that to create the lace edge bunkers you need a special tool. Does it state elsewhere what this tool is?
Mark, ofcourse I have your book, but I had not looked at the simpson section yet. If you have any old pics of Simpson that would be great.
Bill, Colt bunkers had more simple shapes (oval, triangular), McKenzie bunkers often were larger than those of Simpson. Simpson seemed to like longer narrower bunkers often closely wrapped around greensides
