Hi Son,
I checked under the bolt handle and it does have the X1940 on it so it is all together it is at the Dr's getting the bedding checked over as I just slapped it together and have probably put 60-70 down the tube since I swapped the stocks so thought I had better get it checked just in case I was damaging the draws or anything else for that matter.
Cheers,
