we all know it was used on the SM300, but there is a question on whether it was ever officially used on the speedy. there are some pics and owners like Jeff with lollipops on their 2998's, but none of what i would consider the definitive ref books like the time capsule show it or mention its use officially. Chuck's site makes no mention of it either.
i can see no evidence that it was ever put on a speedy at the factory, but i may well be wrong. please tell us the answer, we need to know
best
