With Rosslyn's assistance I have managed to fill in the other answers save 6D *(6) wine containers curate's blessed before leaving - I have C?UATS - have been through Chambers t wice and can find nothing that fits - the A could bd O if 15 across is stretto as opposed to stretta - haves tired those permutations too. Have consulted Wikipedia too, all to no avail - any wine buffs about?
Thank you very much indeed folks! I could have saved myself a lot of trouble if I had read the Chambers bit on Stretto etc properly - saw stretti and stretta but strette was right at the end and I missed it!
