Pursuant to Dean R.'s comments about "ball grips" as opposed to Mike's comments about ball grips.......ahem.
My lifters with true ball grips are called pistol grips within the letters. If we recognize grip structures changed over time (ball, capped, round) and yet pistol grip is used in my letters for most of these from the 1800s to 1940s (exception is where capped pistol grip is called out). Yet the grip styles/structure are very different.
We also know that styles of comb structure did change over time even within the lifter period. Whether the names changed with them seems not as clear. Further, I have never received a letter calling out the comb structure even though I have a couple which would be called full or trap comb.
Obviously, I don't have access to Parker records, but I suspect comb was not documented in the same manner/frequency as grip structure. No matter the singer performing the act.......
