The gears are as follows and contain all set screws and show only signs of normal use/wear unless noted below:

18656- this is an older gear for a Nikon 200mm micro lens focusing- had it custom made by Aquatica and it is not anodized (still silver) 3" inner diameter (id)

18672- for Nikon 15mm f/3.5 Manual Focus 2 5/8" id

18674-for Nikon 20mm AF lens focusing 2 3/4" id

18675--this is the 2/3 wrap variety (not a complete circle like the others) and fits the Nikon 24-50 zoom lens- a killer lens for fish close-ups that can be found on ebay at a reasonable price and uses the same ext ring as the 105mm macro- gear is 2 13/16" id

I also have an 18619 aperture gear that was used for Aquatica 5 and later housings- consider it an extra freebee from this fall clean-out effort.

a google search may bring up other uses for these that I dont know of- $55 takes them all with shipping included to US addresses- if overseas, add $10 to cover extra postage.

First confusion- extensions such as 18458- I have an older version, 3 inches long (3 1/2 with bayonet part); backscatter lists the item as 3.25 inches ( I assume 2.75" with the 3.25 being the length with the bayonet part of the ring); Aquatica lists the item as 2 1/2 inches and 3 with bayonet. 2 questions arise
what is the deal with all the different lengths available? and can mine be used for a Nikon 16-35mm zoom lens and if not which of the other two listed can be?

Second confusion- have the Aquatica gears undergone a number change or is there a new line of gears for Type 4 Nikon cameras- they seem to have the same numbers as the older gears with the first number changed- for example the 18722 gear that I have has been replaced in the newer catalog as 48722. Are these new gears or just changes in the numbers and the old gears that I have still work?

I have a D800 housing on order and really need to know what all I have to update so any help is appreciated in advance
thanks

I need the newer than year 2008 version for a 14-24mm lens.  I can either offer a fair price or an even trade for the older version of this tube which is 3" long instead of the 2 1/2 inches I require for the zoom lens.  The older version was custom made at the time for a kenko 2x pro teleconverter/105mm macro lens combo, allowing the focus ring to match up exactly when using the macro port.

Would make a great backup, second or slave strobe for somebody- I am downsizing and dont need the number of strobes like this that I have anymore- quite a few body scratches on it from lots of use- all cosmetic in nature, strobe was never flooded. Takes 8 AA batteries and has a guide number of 22 (if I remember correctly)- a web search ought to get you any background info you need. comes with diffuser, o-ring for both battery hatch and cable connection port and the arm connector screw and front end diffuser. Slave capabilities as well as Full, and 1/2 power settings (TTL if you still have a film camera). $125 + shipping. US sales preferred for now.

Just thought Id give a heads up here to an item found in my basement which is up on the bay currently at a price that is a steal if anyone is interested- an Aquatica A90 housing complete with camera body- the dual 5-pin Nikonos style- strobe bulkheads are probably worth the entry price alone.  The housing was for a black and white project that never materialized a few years ago- but could also be used for a DIY project as well.
