I see this is an old post but thought it deserves at least one reply...
ordered a very similar setup from Seyberts last year.
OB Pro, collarless and unbranded (special order), matched up to a collarless Players Sneaky butt (SPSPR).
Had to explain what i wanted over the phone. The Seybert's agent made sure the shaft stain and finish matched the butt.
a very sneaky setup: the giveaway (besides being a two-piece) is the short ferrule for the OB Pro.
I think the total was $275.
