<<FYI:
In the UK we often use Faber cylinders.  They are 15 litres water capacity (WC) 
and WP of 232 bar, 3365psi (=123 cuft).  They are stamped as weighing 16.5kg 
(36lbs).  Price about 150 UKP each.
As far as I know, neck threads are 3/4BSP or M25.  I don't know if they do 
3/4 NPSM.>>
     
I was told by Scubapro that there 95.5's (the same tank as Dolphin 97's and OMS 
98's) are one and the same as the European 15l tanks. Since there is more than 
one thread standard and "Europe" may not include all contries over there, can 
you comment on whether these tanks have different ratings in different 
countries? Also verify that the Eurpean 15l tanks are one and the same as the US
2640 tanks. Lastly, the HP 300 Bar tanks. I presume a new tank run and not a 
re-certified tank already on the market?

     Sorry for the delay - e-mail overload!
     
     I don't know whether the Faber tanks are exported to the US and down 
     rated for US Standards.  The best way to find out would be to see what 
     the empty weight of the respective tanks are.
     Certainly the Scubapro 95.5cuft @ 2640psi = 15l WC.  And Faber is an 
     Italian company.
     It is my experience that of the different makes of steel tank around 
     the UK, Faber make the lightest for the same WP.
     
     The new 300bar tanks are not re-rated, they weigh significantly more 
     than their 232bar counterparts.
     
     From what I can remember, a 7litre 232 bar Faber has a TARE of 8.2kg
                                    "   300       "        "       11ish kg
     
     IF IT WOULD BE USEFUL, I WOULD BE HAPPY TO COMPILE A DATABASE OF 
     CYLINDERS FROM AROUND THE WORLD, AND KEEP IT UPDATED ON TECHDIVER.
     ALL I WOULD NEED IS FOR PEOPLE TO SEND ME THE FOLLOWING DETAILS OF 
     THEIR CYLINDERS:
     
     MAKE
     MODEL (eg "104", "15L" etc)
     MATERIAL
     WATER CAPACITY*
     WORKING PRESSURE
     TEST PRESSURE
     TARE WEIGHT (ie Wt stamped on the neck, the empty weight without valve)
     * OR FREE AIR CAPACITY AT CERTAIN PRESSURE AND TEMPERATURE eg 104 cuft
     NECK THREAD
     CURRENTLY ON SALE OR NOT
