Help with Quarter Pound identification.

[ArtieToo]

Here's a segment of the pup id chart:



My QP has the SSL4 sticker on it, and I can see by looking that its a "flat - tapped", but it also has, stamped, (as in pressed into), the base, the designation: 4TRW

Does that mean I have a RWRP? And, if so, what would be some of the ramifications of how I use it? I was thinking of using it in the neck position along with a humbucker in the bridge, of a simple HS configuration.

Or would I be better off, to get a non-RWRP, and use them together, neck & middle?

I appreciate all thoughts and comments.

BTW - The complete sticker says: IFC55 SSL4 0250
