These gloves are 12oz. They have a B/Y logo.  Not sure of the brand - never heard of B/Y. There is a small hand-wrintten inscriptions near the wrist.  One appears to have initials,  a date of 5/11/81 and some numbers below the date.  The other is the same,  but the date appears to be 5/16/81. One has a split as shown in the photo.  These are for display only.
