That’s a beautiful table! I hope you can find a spring. There are a couple of people on the garden thread who seem to be very good at finding odd parts/things - maybe they could help.
Mom is very fond of the Army table. It is solid wood, 6’x 30” & very heavy. Dad got it at an Army surplus store early in their marriage and it was used for their dining room table until they could afford a dining room set. It’s been in various places/sheds & I wanted it for the shop. Now (somehow, because I wrangled it by myself) it’s here :-)
Lots of memories in those old tables. Comforting for me along with more than a few older things I still have. Like my mom’s original hope chest from the 40’s and her cabinet sewing machine that I learned to sew on. I refinished both and took the lock off the hope chest and found a lock business nearby that made a new key.
