Here is an untouched original transfer, looks pretty much centered to me. BTW, if your engine number is not a fair bit above 9900, you should NOT have the "Vincent Engineers" Mercury Crest. Bikes in the high 9800, low 9900 range of engine numbers were built in late 1952, and I don't think the firm name was changed to Vincent Engineers until part way through 1953. Very, very, very few Series C machines should have the Vincent Engineers transfers.
