This sure looks interesting, I don't have any of those in my collection.

That's a good price on the Union Special from what i have seen.

I have one of the 29-4's and it is AWESOME. I only paid $100 for mine (and a one hour each way drive in the Cherokee) The ability to stitch in 360 degrees is really cool.

I helped my neighbors daughter out with some work on her Jeep, and when the mom came over with a dinner as a thank you she saw my "collection" and said "Oh, I have one of those 29-4's!! I bought it 30 years ago and I use it every day in my reupholster business." She showed me the seats in her daughters jeep where she completely replaced the original material.
