Hi I just sold the old 29-4 to a gentleman in Milwaukee WI. I found a Singer 7-34 it dates back to 1924 it will sew over 1" of leather. This machine was rebuilt in 1995 by the Singer Company and was set up with reverse, the gentleman I bought it from used it to make and repair saddles and harnesses in the Upper Peninsula of MI. This machine is in very good condition I was very lucky to fine it. The drive up there from IL was about 6 hours and was worth the ride.
Thanks BattleAx
