Another needle that is compatible with W&G chain stitch sewing machines

I scored big at a yard sale this past summer. I bought a small  green box of Singer

(Simanco) needles in size 25x3 without opening them until I got home because they were sealed in plastic. I didn't know which machine they would fit, but I always buy vintage  sewing machine needles if they are cheap enough and are in their original packaging.

Imagine my surprise when I got home, opened the box and I saw that they looked like Willcox & Gibbs needles! I tested one and it works perfectly. So if you see a box of Singer 25x3 needles somewhere, buy them! :o)
