So I have my recently obtained H&S waffle iron with high bailed base in front of me all nice and cleaned up by Chuck waiting for me to fire it up.
1. The bail? In my view the purpose of the bail or any hand typie on the base was for transport and moving it around, from and to the shelf, etc. The idea that the bail can be used to lift a low base iron on a gas/electric stove to allow you to still rotate the paddles is secondary and not a specific intention of the design IMHO.
2. My paddle set, which is the one marked 928 and 928 with both May 18 and July 17 patent marks and #18 on both is the set with no tab.
3. The hi base is marked as #88, does not have notches for tabs anywhare. The cut out where the paddle handles rest is a square cutout. This cutout has a flat bottom with a dentent into the center. The paddles have a corresponding flat area at the handle with a raised line/nipple that sets into the cutout/dentent. You roll the paddles and they settle into that detent and remain stationary without rocking.
4. So IMHO the proper hi base for the H&S paddle set is the #88.
Hope this helps.
