Help identifying 70s Turler VC

I am looking for some help identifying the following watch. It is a “Turler” in stainless case. Photos of caseback interior and movement attached.
 
It strikes me as original, but the shop selling has “original” papers from 1973 which match the caseback but not the movement. The caseback is marked with two numbers, both of which match the paper. Am I correct to assume that the movement has likely been swapped out? If so, any help identifying appreciated. Also, was it common to double stamp the caseback interior?
 
Any comments or help appreciated. Very nice watch and good movement, but trying to figure out exactly what I am looking at.

Hi and welcome. The double numbers on the back indicate

the case number (474797) and the reference number (6566). However if the movement number does not match that means the movement was swapped at one point or the other. If you give me the movement number I can check if the swap was done by VC or not
Wow...Alex, how on earth does VC Keep so much info on

Each and every timepiece and whether movement swaps were done by VC or not? I'm amazed.

Thanks Alex, I am impressed by the depth of VC record keeping. I only have photos to go off of and the first digit is especially blurry but to my eyes it appears to be: X48804. My best guess is either a 6 or 8 (or 0?) at the front. Not terribly helpful I admit.  Does a 1970s stainless automatic Turler VC in condition as shown above pass your sniff test? Thanks
if the movement number doesn't match the paperwork then it is a

Mine too; when in doubt ask for a second opinion. Lovely watch that I quite like, but thanks
