I know these buggers are unobtanium, but does anyone know of something else that will work--A plain Model 29, not A or B??

Go back 50+ years and I spent 4 summers working at a boardwalk shooting galary on the Jersey shore. We used model 29s and were constantly replacing lifter springs. My last summer was 1969 and my boss gave me a Model 29 as a going away present. "Just needs a lifter spring", said he and handed me one which I dutifully hung from the trigger guard and kind of forgot about it. Fast forward 50+ years and I find out it's a spring for an A (or B?) model.

Best I remember it's a pretty simple wire "V" spring, not the coil spring I have. Is there a work-around anyone has come up with?

Thanks everyone!
