Aaron!!
VERY NICE ARTICLE!! i love those CDBA's and someday hope to own one. instead of the original round lead weights, have you considered getting a mold for 1lb cannonball fishing weights, and making them without the wire eye? that could help prevent the originals being "lost". you may well be able to find the cannonball lead weight molds in larger sizes if you needed to. just an idea.




Iain you may want to look into what the vintage scuba divers do with their double hose regulators, and the duckbills in then in particular to preserve them inbetween use. the duckbills were notorious from my LIMITED understanding, for getting gummy and going to !t. also if someone has any info on care and maintainance of the old vintage frogman drysuits, that may of of help.

some links that may be of use for you:

Vintage Scuba Supply.. they have a great forum and alot of helpful people, IIRC there is even an old PJ on there with ALOT of realworld experience.

Replica Drysuit.. maker of replica vintage latex rubber drysuits... the owner, i believe is William Sewell, is also a rebreather diver, and has a very nice homebuilt ARO-57 clone. he has some videos that can be downloaded as well. quite a nice guy when i emailed him for information on his suits. his o2 rigs are listed on JWB's site under the NL_ Database Oxygen Rebreather section. he may be of some help.
