Ty Engine Serial Number Question

Looking for an answer, I have a TY250 with engine serial number consisting of a "2 digit number" followed by an "arrow". The number is appears stamped in with a flat screw driver or punch. The vertical lines under the number look original, I have another engine to compare it to. Does this mean the case was replaced with a spare part? Has anyone seen this type of numbering?
