You have (according to my magnificent new Model 69 book) a Winchester Model 80 A or B (depending on dia. of aperture) rcvr sight, in the box for the special Lyman rcvr sight made for 69s.  The Lyman sight was a factory option for 69s, but this gun was apparently purchased with the Model 80 sight, then later retrofitted with the Lyman, by a contentious owner who placed the original sights into the Lyman box, rather than tossing them into his parts drawer. 

Front sight appears to be a Winchester Model 97B, of which there are several variations I’m not competent to disentangle.

Thank you Clarence !  Itook a screen shot off Classic Firearms and Parts web site so it looks like a Model 80A according to them.
  

You’d have to know the dia of the aperture to distinguish between A & B Model 80s; as we’re constantly brainwashed by our gov’t, discrimination is evil, so I’ll just refer to them all as Model 80s.

How do I measure it so I know which one I have ?  

So you insist on practicing discrimination?  Ap of the 80A was .080″ dia, but the 80B was available in FOUR different sizes, .052 through .0225″.  The multiplicity of 69 sight options is bewildering–should think it gave workers in the assembly room fits.

Since you apparently don’t have a set of pin gauges handy you may be able to press a set of drill bits into service to approximate aperture sizes. I use the base to avoid damaging the finish.
 

Smart idea!
