Is this an original Murray tag for a 1929 station wagon?

[Neil Mylar LakewoodCA]

This Murray tag was on the inside wood under my unrestored 1929 station wagon front seat.

I thought the number should start with 150, not 250.
Could it be original, but the installer stamped a 2 by mistake?

There were 4954 station wagons made in 1929. 4048 is under that number.
