I envisaged blanked off dummy vents but upon comparing the pics, I realise it was completely absent. Good observation Seanoss, never would likely notice unless I got a collection with the two variants. The only other variation I have observed is the different shape raised border for the powerplus label on the later black version.
Here's my sole Corsair style mould. It has a thin layer of UV degraded plastic I want to scrape off before I paint it.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
