Hi Tom,
Your memory serves you correctly. The cast blue acrylic that is 0.030" thick is very difficult to find.
I did buy a special order at a very high cost (>$1000) and then sold off pre-made filters to recoup my cost of the raw material.
The remaining dwindling stock I use for my own refurbished scopes that I sell.
When someone sells filters on ebay I usually order one just to see what someone else has done.
The filters from Australia are thicker that the original Tek 0.030" and will not float in the bezel.
So they need to be taped into the bezel because they will not work with the spring.
In addition the very tight horizontal dimensions are not maintained - so again the need to tape the filter in place since it will not fit in the bezel properly.
I would be willing to sell a filter to groups members through epay for around $15.
