I've never noticed Worrlocks had that "W' on the vertical asa / frontblock. It's might be a semi-rare part. The straight ASA mini-frontblocks are already hard to find, most of them are the 15* frontblocks found on Orracles and Black Magics. With that in mind, it's probably worth around $30-$40
The frontblock screw (or banjo bolt if you prefer) is also special. It looks like it might be a Macdev screw which allows the LPR to be threaded into the screw instead of the frontblock. I'd guess it's worth $20 by itself.
So you got yourself a nice little parts lot worth up to $60 there. You just have to find the right buyers.
That's what I was saying earlier, I've never seen one like it either. I cannot even remember seeing a Worrlock with a straight ASA compared to the 15* ASAs that are much more common. So it might not even be a Worrlock frontblock.
I don't think Works ever used this style 1 piece frontblock, and they were a little early for this style anyway. It could possibly be a Warped Sportz frontblock.
Regardless, you have some nice parts there man. Put them up for sale if you aren't using them. I'm sure someone is out there who needs either the frontblock or screw for their project, and who would happily pay you a premium for that part.
