Paul. As an armourer , you're lucky to have more than one finger !
Thanks Seigfried and Paul. That's exactly what I needed. I got a beautiful No 36 with a WW2 plug. I collect WW1 and needed a nice representative sampleI think there's a thread on this somewhere . There's no real difference in the bodies except some WW1 ones have a date cast into them . Internally , the WW1 had either a brass or aluminium centre tube & the WW2 had zinc alloy [stamped Z] . Hope this helps.
They all the same size.its different size filling plugs on no5 and 23mk 1 and 2 compared to the larger 23mk 3 and 36s fillers.but the baseplus are the same size.look out for israely no 4 grenades as they look like a mills but take a larger base plug.Regards Darrol.
