Hey whamac,
Your chest is an O52, 7/3 drawer, and your base is a B2104. Click on the link below and you’ll be able to tell what year each were manufactured. Good luck…….toolboxted
BIG NEWS for Gerstner #52 Owners – H. Gerstner & Sons (gerstnerusa.com)
Hey again whamac, I answered too quickly and goofed up. Your chest sure looks like it’s 26” wide making it an O52. Is it 26” wide? But, I can’t find a Style # for a 27+” wide base with 3 top drawers and 1 bottom drawer. Also, the link I added didn’t work. So do this – The stencils on the inside of the bottom board of both your chest and base has been defined for what year your chest was manufactured. You can easily find out for yourself by going to Pg 10s in ‘The’ Guide. I’d appreciate your posting pictures of both stencils. Enjoy……..toolboxted https://sites.google.com/site/theguideforwoodmachinistchests/
