Union Special 43200G and 39200AE - & old amazing sewing machines from yesteryear

With any kind of industrial process, machines come and go and get replaced with time. The Denim Production process has quite an interesting history, as for the last 30 years not only have the way we produce denim been modernised, from lovely Shuttle looms to modern counterparts, but also the way we make jeans from older sewing machines and the transition to modern industrials sewing machines.

There are so many little touches which have been lost when we modernise. When i look at old vintage denim styles, one thing for me stands out, Wow that stitch is amazing ! Researching and learning which machines created the styles has become just as important for me as the fabric its made on. You got to understand the past to move forward. Its one thing to use to get Antique looking denim, made on old drapers looms, but a whole other thing using vintage machines to make them… I have been slowly buying up / and finding out what machines I need for my studio, and nothing seems to get me excited like a "Union Special" Sewing machines… Simple things like button holes, bar tacks, overlocking stitches, roping effects /skewing or buckering on hems of jeans, irregular tiny stitches are all super amazing and fresh today. Most Brands Like LVC / John Bull / Kapital and 45rpm are only using these types of machines to make there collections on, its easy to see why.

This old Levi's denim pant, notice the small tight "SPI" stitches per inch...

modern denim is nothing like this...

Modern industrial sewing machines fall flat when it comes to these small details… These older machines were to slow and labor intensive operate, but produced very unique characteristics in the way the denim was produced, which cannot be fully replicated now. There are a number of amazing vintage sewing machines, but I just want to touch on two…

1st is the Union Special 43200G.

This is particular model was used for chainstitch construction. These vintage machines are still some of the strongest machines out there and highly sought after worldwide. This particular model can go from anything from 5000GBP to 10,000GBP, only because of its unique pushing and pulling style of sewing, it is indispensable. This "push" and "pull" creates directional pressure and is used to sew areas along the waistband, hem, and other parts of the denim. Along the hem, the directional pressure will create a roping effect, and it is this "roping" makes the machine so special.

My friend Rudy who owns one of the best denim shops "Son of Stag" in Brick lane, London with his UNION SPECIAL 43200G

There are 3 or generations of types of 43200G

Below is a video of Roy Slaper of "ROY"- Denim Nut, who is amazing on another level ! Roy is making all his denim the old way, and he has slowly got all the old vintage machines.. its super inspiring looking at what he is doing and achieving to such an amazing level... just notice how many machines he is using, esp look as he is using a Union Special 43200G at 02:05...
