I bought it. The whole outfit is in beautiful condition. The "B" is very out of collimation. I knew I was gambling when I purchased it and even though it is in very collectible condition, I lost the gamble. The performance of the objective makes me very sad.
The reason why I did not post was I really did not have anything nice to say. I am still sad.
Very disappointed to here that about the lens Dan. Was really expecting and wanting to hear great news along with a massive photo laden post. I really wanted to take the plunge initially as well, considering the outstanding shape, rare accessories and the fact it was a triplet “B” objective. Just too much risk in the end without being able to look through it first for me, especially with the potential B lens collimation issues I’d read about and the shipping distance. Probably not much consolation but that still IS a very rare, beautiful, highly collectible and exceptionally fine condition scope. Zeiss ability to figure, polish and assemble such a lens back then is an astounding testament to their skill and an amazing piece of astronomical history.
