...made me curious about Williams woodie legs which I'd thought I'd figured out, but it turns out not so much thanks to everyone's excellent feedback...yes, both here and on Spinside. ;o)
Anyways...I recently moved my storage location to shelf in my workshop for all my wood legs. This allowed me to line them all up by length easily since they all backed up to a wall, and therefore stuck out different lengths. I found out ALOT about the legs I THOUGHT I had, and how badly these got mismatched over the years. I had lots of legs marked as WLMS that were actually GTB legs - which I still believe are ALL 31" from just before the first flipper games, all the way to Harbor Lights(first metal leg game).
But Williams is a different story. Basicially, it appears that they changed the leg length everytime they changed the cabinet. Thier first flipper game(Sunny/Stormy), and the next one Tennessee, had an older flipperless style deeper cabinets, and shorter legs...I believe these took 30" legs, but being such a small sample, and the fact that I don't own alot of flipperless, I'm kinda assuming the length on that one by what I do have in stock. But after Tennessee, they changed the cabinet, making it much shallower...these games continued for a couple years until Pinky near the end of 1950. These game's cabs features no motor board, and everything is attached to the bottom of the PF. Another way to tell on the outside is the rails on the head are flush...after Pinky they stick out on the edges and top - making them a PITA to store BTW. :o)
When WLMS changed the cab to make it deeper, I think to accommodate the re-added motor board, the cabinet became one inch deeper - I verified this on games I own. I believe this is when they switched from 33.5" legs, to 32.5" ones that they continued until they went to metal legs in 1956. This makes sense too, not only by judging the ratio of legs I own to # of years they used those legs for, but also since in the end you wanted all of the games to at about the same level. I believe the GTB cab was just slightly deeper, or maybe it's bolt-hole config was slightly different too, which would make them close to the same height when set up.
I used my 57(!) sets of wooden legs, and my own games, and ALOT of IPDB research to come up with these findings...please provide feedback if you agree or disagree.
I also found out through this re-org that I have many extra sets of GTB legs...and not enough of either kind of WLMS legs. SO...
If you need 31" GTB legs, and have some 32.5 or 33.5 inch WLMS legs you like to trade with me...please LMK! I go to the Allentown and York shows every year and could meet you there easily....shipping might be expensive, but I'm not against it outright. I'm also obviously not in a huge hurry...
