Tons of info and pictures on the "All about guns" forum at spearboard.com. Also some good basic info on Bill Kitto's old site:
Internet Custom Spearguns
and the new, updated site:
Internet Custom Spearguns
This guy has some nice guns and sells partial kits that you can machine, install the mechanism, and finish yourself:
