SP Star Polestar Grey

Now these are weird. This is the first SP Star nameplate with their full name as opposed to just "Star" but it's in a different font than the more recent blue or grey housings. I'm not sure if these were sold separately originally or came from a Leopold board, but this batch is desoldered from something.
