My questions is:- I would of thought obvious, does anybody have any idea, What the hell is it, or what it was. Were there any rifles like this, produced by the factory. If someone knows what it is, What's the Correct barrel length, for whatever the hell it is, great. If you ask for a particular piece of info, I can supply it.
I understood all rifles like this were produced in 308, and that's all I find any mention of. These as I understand it had either stock length barrels, or much longer even heavier barrels with the steady rest groove. My barrel being shorter doesn't need a steady rest, so no groove. I have not seen many L series rifles, but I've come across some DCRA rifles and a couple of those were in 303. So is this a similar instance.
My other 3 No4's have slimmer barrels, none of them have a sudden increase in CSA behind the front sight,and they are all different barrels, types/makers. This barrel is on average 0.1 inches thicker over it's length, my micrometers read to .001mm, and I've been using them for over 30yrs. Behind the sight is 0.5985" , the Dia increases to 0.6455", in the space of a 1/4 of an inch, do you want the trig for the angle, or will that suffice.
I have read about No4 T's having heavier barrels, could this barrel be one of those, left over and used here, this barrel has a production date of 1953. As I've already stated the side of the receiver is milled flat, as if being prepped for pads or a target sight, which means mine will fit nicely.
The serial # seems odd, Even by UK standards of the time,it seems sad, could it be a valid #, or some others concoction. If it's a stock type serial# for a 1955 Faz No4 MK1/2(FTR), then did they have, or were some fitted with these heavier barrels. If any actually existed.
I have heard of other companies modifying these rifles at the time like CAL and EAL, this rifle has no markings like this to give it away, as one of these.
What am I curious about ? the rifle, isn't that the whole point of this website, correct if I'm wrong pls. If you have decided this is not worthy, just say so, I think there's enough info the with make, yr. type serial number, dimensions to form an idea of what it is, a photo isn't going to give you a dimension. I re-read my original post , my question was plain, even though I was not sure what particular rifle I was dealing with, I phrased it as an appeal for information to any one who had an idea. That's the main reason I tagged it on to what seems it's closest relative. I only seek help on forums when stuck, preferring to do my own research, but access is not readily available, is it.
If you have an idea what this rifle is I would appreciate knowing, but if you think I cannot live without knowing, I'll enjoy the rifle just the same, as I said just curious.
If you have some info, I've Got some some pictures. Regards Ian

If you have some info, I've Got some some pictures.

Photos will do more than several pages of text IF they're clear and show good detail! Esp. markings and any other machining peculiar to the barrel and receiver body side wall.

I have never heard of HB No.4 Mk.I(T) s before. The Australian No.1 did have a heavy barrel variant, but obviously that's not what you have.

Curious, but it's doubtful it's a military variant you have.
