Hello Fred

 

I have no additional information on the first generation lens.

 

However, looking at photographs the knobs look the same, although both are silver.

 

I have a Nikonos 15mm ver2 which I have as a parts donor.

 

Send me a PM and I will donate the knobs, control shafts and screws for your project. You could then drill out the seized ones and hope for the best! I don't have o rings, but there is a fellow on Ebay in France who sells them.

I have been using Lanocote on threaded metal fasteners.

 

It is basically a waxy material made from lanolin and seems to work like a charm preventing galvanic corrosion.

 

You can buy it from boatyards for marine hardware and Backscatter stocks it.

I used Seavison in San Diego.

 

They did a great job; distance correction upper, plain glass lower.

 

Find a mask with tall lenses (e.g. Scubapro Spectra) to give more real estate.

 

I also had them bevel the lower edge of the upper corrective part, so looking downwards I am looking along the bevel, rather than across a flat, distorted transition. It gives the impression of no correction and makes more of the surface useful for vision.
