Where can I find a copy of the letter from the Steipler telling Collel Chazon Eish not to make rounded luchos rather square ones as is mashma from the gemora on this daf. I have found R. Shach's letter and R. M. Shternbuch's teshuva both quoting this letter but I have not been able to find the letter itself. I need it by monday afternoon. If you know of any reasons given for the minhag of the world to round the luchos I would really appreciate it. Thank you for your time and effort. I have no access to Yosef Daas on Babba Basra otherwise I would have looked there as well.
