Hey Jaye - grab a coffee (long reply) Coffee Break2
Unfortunately - No, I'm not sure.
I'm a newbie to vintage drums and limited to what I experience from the drums I've acquired.
I got this 26" Rogers Yorktown from a barn back in the mid '80s, and it's sat in a closet "as is" since then. It was from a school around Levittown, PA. - Who knows what went on during its 10-15 years of use re: parts.
As for my Slingerland 18" - it sat in a church storage space 'til I got it in '04. It's missing one wood hoop, but the key rods & claws were attached. - - In both cases, neither drum had heads, but the rods & claws were 'finger tight' into the lugs for safe keeping.
As a result I can't be sure, but just kinda figured they were original.
Of all of the claws that I have from both drums (21), they're all the same except for 3 that are obvious after market replacements.
As for the other 18 total that I have, I've had 8 on the Slingy since before it and the Rogers ever met, with its others put aside in my parts box.
As I compared Rogers ones with those from the Slingy, they all seem identical. (see pics)
The only difference in any of the claws that came from both the Rogers & the Slingerland collectively is that most of them have a shaft length of 1-7/8" - with 5 or so being a 1/32nd of an inch longer - a practically invisible difference. Probably an acceptable "margin of error".
All this to say - No, I'm not sure.
I did see a picture of a Rogers Powertone 26 x 10 bass that had the same claws that I speak of -
But you're question has me searching for Slingy pics with the same claws - and, as of yet, I haven't found any for sure - Perhaps my Slingerland is atypical or someone swapped them out from the cone type, although I don't know why one would ever want to.
My Slingerlands are like the 1967 catalog "Jet" Outfit, BUT ~ my bass drum has wood hoop(s) with matching champagne inlay - not the chrome hoops. My date stamp is blurred on the last year digit - definitely not a "7" - I've sorta assumed that my kit is a '66 or '68 that had a different hoop option.
So maybe my Slingy claws are not original.
You've given me a different direction to think in, perhaps the real question is: Did Slingerland ever use this style of claw?
