Tom, both serial numbers of your gun are in the A and B serial no. range. I would guess your 3538 has engraved dogs, rather than etched. I think the Infallible trigger could have been an option supplied by the factory. It was a somewhat better trigger, design wise, than the Baker one. R grades were from a period when Baker marked the grade on watertable.
