Replacement front guard for VBB


could anyone tell me what the difference is between the following two front guards for a VBB on offer here at SIP.

ART PV1525 says it's a reproduction but it's more expensive than the so called original one.

ART 76025000 this one says it's an original vepa part, but why is it so much cheaper than the repro one?

Any help on this much appreciated.
