BN1 Diff Ratio ID on Housing

I know its there somewhere!, can amyone tell me where the numbers are stamped?

I don't know if you have the early BN1 spiral bevel axle or the later hypoid type. On the hypoid axle the ratio is stamped on a flat place, near top center. Attached is a pic of a 10/41 axle.
