Came with a box of K-model parts, are they for a 45 or?
Can't quite make out the one number, 428043, 438043, 488243?
Thanks for any help.

Not K model - K model would have a 4 bolt flange. Probably 45 but possibly UL on the smaller one. It would 428 something.

frichie68!

The end that you have the caliper upon should be the same for all three-bolt 1¼" models, even Scheblers.

The spigot diameters will best determine their different models, but there are confusions of course.

Generally but not always, W models are 1 7/16" diameter, and U models are 1 9/16", yet you must consult your Palmer's to sort out all of the varieties possible.

Just trying to look it up showed me that I must make yet another machining fixture.
