Ok, here are the latest samples in the first picture and the second is a standard BeO type ceramic insulator. They are not perfect matches to the angle of the TO-3, but they do cover the area.
So, good enough, or go back to the distributor and look for a "better" fit?

Just wanted to get interest on a group buy for some TO-3 high performance insulators. Pricing would be $1.54 ea with a MOQ of 400 pieces. I'd sell them in batches of 15 for $25 including shipping costs (estimated cost). You can sign up for multiple batches.
We will need 27 batches / participants, which might be a tall order.
Ok, after looking at the other choices, the above is clearly the best choice!
Ok, now that we have proper size, the prices have changed. The above text reflects this change. Please go ahead and register your interest - the quote is valid for 30 days so we will need to move somewhat quickly.
Please quote and append this list (remember one batch is 15 insulators - the below is measured in batches)
