I have a Winchester Thumb trigger 22 it is pre 1915, not that should matter.  I am looking for a bolt and the thumb trigger bar.  I have seen some adds that indicate  that a model 1904, 58, 59, 60 and the 99 (new model of mine1920-192?) bolt will interchange-  anybody know about this??

Also does any one have the thumb trigger bar or a blue print so I could get a machinist to make one??

 

any help would be great,  thank you.

The bolt from a 1900, 1902 and 1904 will interchange with the Thumbtrigger EXCEPT for the cocking knob.  The Thumbtrigger cocking knob has a notch on the bottom to catch the sear on the “bar”.  You can easily modify the standard round cocking knob and add the notch.

Also, the Thumbtrigger firing pin is different since it does not have the notch for the sear like the 1900/1902/1904.  A notched firing pin will work in the TT but may “catch” on the bolt stop.

The 58, 59 and 60 have a different bolt, bolt handle and sear engagement and, although they will “fit in the receiver hole”, should not be used in the Thumbtrigger since they headspace differently off of the larger bolt handles.

Below is a comparison photo of the Thumbtrigger and standard 1902/1904 sear.  Notice the pivot point is further back on the TT sear and the bolt stop is different.  The component parts sketch is from the 1920 parts manual.

If you have one made be advised that the sear was case-hardened after machining.

Hope that helps.
