The 48-7515 became the '28-48 replacement, following the A and B 7515...difference is a tiny shift in a curved contact. But assume nothing unless you saw the complete number...I had one of each side by side from comparison, and found a "48" on the early one! Flipped it over and found the complete early part number...the "48" was apparently just a forging number or such, and was not actually a 48 prefix!
