Dave, check out the blog "CARPE TRUTTA" (SEIZE THE TROUT), carpetrutta.blogspot.com. While most of the blog centers on Trout fishing The author goes through every step (with photos) on how to construct a two piece, PVC lure similar to a Roman lure. In addition, he discusses the steps to make decals with which to paint the lure. It is fun to read, the author has a good sense of humor.
This is the best example I have found on making a lure similar to the one you wish to build.
Good luck,
John
