That is indeed under the umbrella of shs.
Most techs have moved away from 9mm bearings and moved to higher quality 8mm bearings.
That is likely a lower quality alloy if it's really cnced. That one also isn't a quick change spring.
I don't know if that item will ever be in-stock again tho.
Also avoid retro arms/bloomies v2 shells. The split and the regular one has bushing/bearing hole placement issues. They are unfortunately flawed, even if they won't admit it themselves.
Did you crack a original shell?
