Thanks everybody for these nice answers and for welcome me!
Rob, I've read your very interesting post months ago and your collection is very impressive! I've read a lot of articles in your forum since a couple of years but never post something here. I had to collect more stuffs before present you these pieces. And my English was not enough accurate to maintain a discuss with you guys. Hope this is correct today...

I've also recorded a lot of pdf files in the download section as Navy manuals and US DIVERS catalogs that help me to date and knows these items better. So I would really thanks the members & especially administrators of this really nice and interesting forum!
About the gauge you like Rob, I'm unable to date this item because it's Japan made. Maybe you could help me? I know that US DIVERS give authorizations to Japan to made knife, regulator, gauge,... in the late 60's/early 70's (like the Aqua Master Nihon KK regulator).
Usddude, if you love all the french items as much as I like american items, I advise you to go on Ebay.fr. I'm sure you could find some interesting stuffs. You can also have a look to "Le Bon Coin" website. For exemple :
http://www.leboncoin.fr/annonces/offres ... 5E9tendeur. I've write Mistral regulator in French and find some interesting stuffs. But unfortunately the price is often more higher than in USA... ;(
If you need help to translate words in French don't hesitate to ask me, it will be a pleasure to help anyone as you have help me in my researches.
Bryan, I'm not sure to really understand your post. I'm sorry but as I've said my English is not enough accurate and sometimes some sentences are hard for me to translate. Do you propose me to ask to somebody for these items? Or do you just talk about your own collection? These items are pretty interesting for sure!
DaleC, about your Aquarius I've decide to pass my bid to one similar last week! I was sure it was a model from the 60's but after well reading I found it in the early 70's USD catalogs. But this gauge is pretty nice and I really like how it's look!
Sthtxdiver, you're welcome! I will show you all my new items in the future. I don't dive with all of them because they are too fragile. But I hope to try my Calypso II on December. I'll show you some pictures next month.
Cheers to all
