Chambered in .22 Hornet, early 50's vintage. Question 1: .223 or .224 bullet? Question 2: Number of twists?

bert H should be along to help out...he knows his winnies.
For Bert, S/N is 268xxA if that will help narrow down info.
That will help to closely estimate the year your rifle was manufactured. It will take me some time to dig through several sources to come up with when Winchester switched from the early .223 bore to the .224 bore. The later .224 bore rifles may be 1:14 twist verus the early .223 bore which were 1:16 (I believe... but not 100% sure).
Hornady, Speer, and Sierra all list the 22 Hornet at a 1:16 twist rate (the test rifles were all Savages... Models 23-C, 219 and 340C).
The 22 Hornet rifles manufactured prior to WW II were .223 bore, and thereafter were .224 bore. Those few rifles factory chambered for the 22 K-Hornet (my preferred cartridge) were 1:14 twist, and .224 bore.
All Winchester Model 43 .22 Hornet rifles were made with a .224 bore, and a 1:16 twist rate.
The below picture is a standard Hornet and the superior K-hornet cartridge (after fire forming in my rifle).
