How to tell If I have Spikes LPK

Like the title says, I was wondering if there’s a way to know for sure if I have Spikes LPK.
I looked for some markings and found letters “S S 1” on the hammer, not in order but from the top to bottom, also the hammer has a notch.
Thanks.

I would call or email spikes.

For what its worth my DD LPK hammer is marked S S 1 in the same order.

As do my two DD hammers and two PSA hammers I have. The third PSA hammer is marke S,S,4.

Good luck figuring it out.

My Spikes LPK had the spider logo on all the parts even the detents.:no:

I looked inside my grip and it says Rock River Arms so maybe I got their LPK.
Oh well, I guess I cant complain since I got complete lower for 275 bucks that I ordered back in November.
