My latest acquisition - CLLE Mark1* Pattern 14 .22 R.F.

[Lance]

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?????

The barrel would have left AG Parker with a tubed barrel. Fortunately for you when that barrel became worn it was replaced by a solid BSA example. While technically not a .22 Pattern 1914 Long Rifle anymore yours is the first example I have seen in the wild. You definitely won the lottery on her!
