Thanks Lance. There are no AGP markings on the barrel knox or crown. It Looks like a solid .22 barrel made by BSA has been fitted, which has the same .22 L markings as my Bonehill converted 1890 MLM.
I'm assuming this barrel is a replacement considering AG Parker carried out the conversion to Pattern 14 .22 & would have thought they would have fitted a .22 sleeved barrel with there markings on it?????
