I have these aswell.
My numbers are.
Batch No. 70295
Reg No. 157/48
same as mine mate...had to heat the barrel up though when i'd loaded..thick as fcuk that stuff...stung a tad on it's way in aswell.
Got mine in a little single box aswell..looks neat and tidy,be surprised as fcuk if they are duds being as there seems to be no expense spared on the packaging etc.
All the same info on the vial as the box aswell.
Anyone else know if these are good to go??
