1947 Walker Turner here.The one with the "heavier",full base.It has 32 speeds....16 from factory and we put a two sp motor on it.
It's about 15 or so feet away from its brother.....a '51 W/T 20",production table.
The former is used in machineshop to augment the BP........the 20" is at the end of cabinet shop.Meaning the radial is close to cabinet shop....the 20 is near metal shop.There is only a small amt of wood done on the radial.Probably because of the net worth of the 20?
The radial does however have a lovely layout table.No it's not pink granite,but for down and dirty layout and fixturing it sees almost daily use.The benny to this overall design is that you get to utilize the table "more better",because the drill head/arm swings out of your way.And occasionally use the chuck as part of a metrology setup(the tilting axis).
Ours is near mint condition,bought off C-list for beer money.It takes an inordinate amt of space/realestate,and is stupid heavy.......I'll keep it because it gets used right much.But would say 90% of folks would be way better served with a big honkin,"regular" DP.
Edit to add;The 20 has "power downfeed"....and if you ever get a chance to look at a W/T with this feature,it's rather interesting.
