I have a Takahashi telescope cradle that has been kicking around my observatories for the last 8 or so years. It is 110-115mm in diameter (depending on where you measure it) so it was it might fit a TSA102. I have had a few Takahashi scopes since then so it is a bit of a guess.
I am happy to let it go for $110 including postage. It has no damage at all that I can see.
