Info about this #4 MkI Sniper rifle.

I've been reading on here about this gun and could use some info. if you guys can help me out. Its been in this box for the past 35+ years or so and I just took it out.
The serial # is A1391 and so is the bolt. The stock is stamped 3274 behind the bolt and the underside behind the trigger guard, looks like it might be: C JC 3B S S.
It has a check piece screwed on and has a brass butt plate with a trap door containing a brass oil/grease can.
The scope box and the scope do not have matching #'s and the scope has a blue B written on it.
I gave it a quick cleaning after I took these pics and most all the rust cleaned off.
Can you guys give me any info. about it and possibly what it might all be worth?
Thanks, I'm a new guy and don't know too much about it.

It's a 1931 No.4 Mk.1 Trials Rifle Sniper Conversion (T). Quite rare. Last one I saw at action sold for $6,000. :dancingbanana:

Don't clean it much past stopping the rust! It's actually in quite good shape from what details have been shown. Value of these can only be determined by selling it at auction. But it's apt to go for quite a bit.

I agree you have quite a find there. Any No4 T is valuable but a Trials rifle particularly so. The scope is mis-matched, but that is hardly the end of the world. I would also reiterate what JM has said - please don't over clean it.

Well done!

OK, I appreciate the info. and I wont clean it too much, like you said.
Now, next question is: What/where type of auction is the right place to sell it?
Gun broker, Ebay or is there another place that specializes in these things?
Thanks again,
Chuck

Gunbroker is the best place here in the states. You might want to solicit private offers on sites like this or Guns America. You first have to determine what you are willing to let it go for.

Here's an MKL entry worth reading for research and comparisons ...

With thanks for the research analysis and assistance of Advisory Panel members Lance and Roger Payne, there's an entry in the United Kingdom - Milsurp Knowledge Library (click here)

Some more photos would be help full to determine how many parts are still in Trials configuration and/or matching like the front nose cap, stock etc. The bolt does have the early style cock with the screw in it which is correct. To get the best price if you list it, you should make sure you include enough photos of all these areas. Ray

WOW, lots of reading for me to do. From what I've read so far and looking at the pic's, everything seems to look "real". Now I have to go back and take a very close look at the points of interest as suggested.
I took more pic's today, but none came out clear, but I will retry again tomorrow.
Can't thank you all enough for your help and I really like this forum.
Oh-- and I probably will be wanting to sell this "package" after I find the truth about it and a few other "things" I have in storage also.
Back to the reading.

Sleeping Beauty! You chose well.

Looks like it might be a REL Mk3, that or CTS...CTS I suppose since it's not "CB" marked, but only "B"

From the bottom of the Chest No15 and the rust spots it looks like things got a bit damp at times?
