I.D. Info found on Intermediate Casing

[Lyndy]

While stripping paint from my Intermediate Casing, I found the following Information on the top of the casing near the filler plug:

2205A

There was the letter "G" couple of inches to the left of this number.

Any clues as to what this number may represent?

Probably a castng number, date code, or internal factory part number.
