Many thanks, MGMRADIO:
The Douglas barrel recollection fits Larry's remarks to me in 2004-2005.
He shared that at the start of his Spencer's he used Douglas 4140 alloy, 50 caliber blanks with 36" twists. He wanted a faster 32" twist, but could not get Douglas to cut it in 50 caliber.
He bought used Pratt and Whitney hydraulic guide bar 1/2B-50 machinery to make his own using either 41L40 or 12L14 alloys.
This transition happened around 1999-2000.
Overall, Larry's Spencer twists were 36"and 32" and there are two documented Hoyt blanks with 56" twist that were specifically requested by shooters. There is a third, original carbine with a 56" Hoyt twist
replacement barrel that the owner posted was Romano's work.
Larry told me he did not do that one, that it was "never in his shop, and he knew who did it".

Edited 30 Oct 21 to correct twist of 38" to 36". Kevin
