I realise I’m replying to an old post but thought the info might be useful anyway - according to my Standard Catalogue of Winchester Firearms, The “Extra Long” stamping was added in 1914 and replaced with a “.22LR” stamping in 1927, so this rifle would have been made in that period between 1914 and 1927.
The proof marks Winchester used at the time don’t involve anything date specific so there’s basically no way to date the rifle more specifically, from what I understand.
Actually, the .22 Extra-long is a specific cartridge. The case is longer than .22LR and held 1 extra grain of blackpowder, 6gr, compared to the .22 Long cartridge which was loaded with only 5 gr of blackpowder. My references say the it was chambered in the Model 04 from 1916. It had the same velocity as a modern standard velocity .22 round. It will not chamber in a .22LR chamber but the .22LR will chamber in a .22 Extra-long chamber. You should never use modern Hyper-velocity .22 ammo in rifles chambered fo Extra-long.
Well, my chassis had finally arrived!
From this
To this!
99% there. Just one more accessory and it’ll be done 
I like that.
That does look good, but then it was already pretty sexy beforehand.
Thats scary looking…Does shoot well?.
It shoots very well considering I only use a red dot on it.
Ok, so not new…
But just installed new trigger spring
I say I hate stripping trigger groups, but I think I enjoy it in a bondage kind of way.
Noticeable improvement.
For that level of risk the reward should have been big. Well deserved. Trigger mechs seem to be on a level with watches when it comes to small fiddly parts.
I need a new 22 so bad people. So bad.
I’m afraid I’m not understanding your comment, you’re saying “A new”, surely you mean “some new” yes??
You can buy my t-bolt or the little old sportco if that will satisfy the jonesing…
The best saying Ive heard is “Your not an addict until you’ve sucked dick for it” JS I think you need an intervention or at least lots of small ones (plinking sessions) lay out all your 22s and use them all Surly this would be enough to slap you to your sense’s or at least realize you have the full set of the collection.
Have one, don’t want the other lol
Ye, well, you know, if there was something worth sucking for… Just nothing specific I really want. There are a couple of trainers I wouldnt mind, but i wouldnt pay stupid money for those. $2k+ for a single shot is just a hard pass. I’m not that into them. Like No8Mk1 floating around, I’d like that, but not for that money.
Guess we wait and see whats on the horizon. I’ll start on the jaw excercises now.
You don’t have the limited edition Tasmanian farm yard gunsmith sportco with streamlined bolt release, though… this makes your collection distinctly lacking!
Also, the t-bolt shoots & handles great; you just don’t know what you’re missing.
I own a tbolt and believe it or not I don’t have a high opinion of Sportcos. 
Well, you need this one to confirm your opinion, then. 
In prime Tassie farm yard condition…
I honestly thought it would be the other way around.
I bedded my t-bolt & put a new trigger in it. The stock trigger sux arse.
No! Denied!
