There was an B&L adapter available that allowed using standard SCT accessories on any B&L SCT rear thread. I had one for a B&L 6000 in the late 1980's. Any standard Celestron or Meade SCT thread on accessory could be used. The adapter part number would be found in the owners manual accessories list.

The problem seem to be such parts,actually any parts, are rare and priced as such. The fellow referenced earlier has few pieces listed online.There is a part or two I may buy after being satisfied the "survivor 4000" is usable.

I agree. I had a 1971 Gremlin X. It had poor weight distribution, but it was a sharp looking car!

An update for anyone interested.
Finally tried the 4000 with unbroken corrwector using the diagonal from another and verified thusly that the corrector is indeed shaped despite appearing flat to the eye.The view through the good one is fine,at least at 40x and 67x but the "repaired" front assembly with plain glass disc resulted in an image that was sharp only in the very center and distorted more the further from center as if looking through water.The plain glass was,of course , with a center hole and the secondary fastened in place as original.It just didn't work.

Wonder what the curve of the corretor actually is ?

If you want to experiment.
Look for a 4" Maksutov corrector, you are far more likely to find one of them floating around than an SCT 4" corrector. Convert the scope into a Maksutov, it would probably be better. Likely you'd have to extend the tube. Just don't pay too much for the corrector as the scope would have no real value itself.
