The Mishnah Berurah sometimes quotes a sefer Shulchan Shlomo (e.g. 489:3 that women should not count sefiras haomer with a beracha since they will inevitably forget a day). Does anyone know who the author of this sefer Shulchan Shlomo is (it cannot be R' Shlomo Zalman Auerbach (though he authored a book of that name) as he lived after the Chofetz Chaim) and/or where a copy of the sefer can be found?
There is an online shiur that deals with the author of that sefer. It is the class dated June 15. http://www.webyeshiva.org/course/the-mishna-berura-and-its-sources/
