I had a 225OT blade and at first glance.... they look the same.
After I got it apart I saw the difference in the blades...... the 125OT blade has a notch for the liner lock to slip into.
(edit)... so I filed the 225OT blade to match the 125OT blade.
SO.... after a good clean up and reassembly, I once again have a nice Old Timer liner lock knife...(even if the pattern number on the blade is wrong....LOL)
I hope this information is helpful.
Thanks for looking everyone.
