Like me some old S&W's. New member first post. Looking thru post for info on HE below. Hope you folks can help. 4.25 in barrel. Serial # 3586xx bottom frame grip & cylinder. Serial # under barrel...B 3586xx. No #'s inside wood. Grips like een on Bekeart .22's. From what little i know, Bekeart's were .22. These grips added or original? Mushroom ejector. Have enjoyed perusing all post. Any help/info appreciated. Just got 4th edition Standard Catalog of S&W. Great read. Thanks from North Carolina.
