From what I can gather in information it was in the mid 40's they went to the 2 3/8-6 as a standard for the 14 1/2"  to match the 16".
But then again I've been told the 14 1/2 was the red headed step child as most went with the 16".

From 12-26-1939 to 9-8-1948 the 14-1/2 spindle was 2-1/4 - 6
Starting 5-26-1946 the 14-1/2 was available in 2-3/8 - 6

Steve do you by chance know the taper on the early 14 1/2" spindle , I know they had a Colet adapter but was curious if any other sizes could interchange or was the 14 1/2 on its own.

Hi John,
During and after WWII, the tapers were all revised to .602 except for the 10R which ended in 1951 with .623 taper.  The taper diameters were .938 for the 9/10K and 1.6295 for the large lathes. 
The older 14-1/2 had the same .602 taper, but the TD was 1.325

Our 14.5" has a set of every 1/16 collets with it, some in poor condition (cracked).  I've tried to obtain others, and one supplier identified them as R4 size and as common as rocking horse manure.  The thread is 0.945" diameter, which is as near as makes no odds, 24 mm, although I haven't checked the pitch yet.

Can anyone confirm the bit about R4 and them being made of unobtainium, please?

Possibly check the workholding section at www.shophardinge.com, they have a lot of collet information.
