I've seen that on eBay for a while now, at about the same price, so on that metric, it's not quite worth it. However, it is rare speed equipment so I do expect the value to be quite high.
It;'s one of those things that is worth the price for someone who wants it for their speed parts collection, or restoration, or period correct replica. If you simply want to supercharge your engine and don't care about any of that, there are much cheaper, more modern alternatives for the same power.
