Lot of Magic Chuck Morse taper adapters, etc. 1-1/4" & 1-11/16" drilling milling

Description

Lot of 9 Morse taper adapters/extensions for Collis Magic Chucks plus what looks to be a drill bit extension. Specifically, you get 3 short 1-1/4" to MT3 (3MT) adapters, 1 mid-length 1-1/4" to MT2 (2MT) adapter/extension, 3 long 1-1/4" to MT3 (3MT) adapters/extensions, 2 short 1-11/16" to MT3 (3MT) adapters, and the drill bit extension.
The drill bit extension has a 5/16" bore and the extension part (blue in the photos) is 9" long.  As the condition description states, they all have various degrees of rust and some of them have been modified by grinding the locking slots or grinding flats here or there.
