Searching for b31 3 bk45 1 92

I'm afraid I don't recognize these codes. Would it be possible to see a photo of the first stamp, the one that starts with "B31?" Sometimes the way the code is printed is just as important as the code itself and that may help me determine exactly what you need.

Thank you! That's a huge help. Looks like that first stamp is "831," which indicates our 24-837 as the right replacement. I am confident that this is the part you want.
