Help! Tracking down aftermarket part manufacturer

[futureworks 864]

Hi

I’m trying to identify an aftermarket alu parts maker for some TA04 purple knuckles, as pictured. The other picture also shows some alu suspension arms, and the common feature for the manufacturer of all of these parts is, if you look closely, how part of the item is left silver, such as the angled inner edges of the cutouts on the suspension arms, and the extreme end of the knuckle. I’m sure I’ve seen lots of parts from whoever the manufacturer is in the past, but can’t remember who made parts with this distinguishing feature. Can anyone help?

The partial silver edges are a Yeah Racing thing, but I'm pretty sure they aren't the only ones that do it.

A bit of a hunt through some showroom entries on the main site and I think it could be Eagle Racing: https://www.tamiyaclub.com/showroom_model.asp?cid=6876&id=896
