Can't tell you about the very 1st 40X, but I own #0030 and another one just a hair higher number and saw another lower than these 2; all of them were stamped with the model number. I've owned over 100 and looked at many others and never saw a 40X that wasn't stamped with the model (except a rimfire model that obviously got out the back door before it was finished or even had a serial number). I still wonder if the model # was sanded/buffed off the OP's rifle, since it is a shallower stamp than the Remington stamping above it.
