Recently looking for reviews of older hammerhead flash units for buying advice, I happened luckily to discover reviews of the Sunpak 555 (in which I was quite interested) in the
current equipment area
Flashes (Third-party) - Pentax Camera Accessory Review Database rather than the legacy area. In fact it had two reviews, both quite recent, although the "stub" of the review may have been there longer. I'm pretty sure that the Sunpak 555 has not been in production for a long time, and looking at some of the other items supposedly still in production, there is other legacy stuff there - a Sunpak 442D, a Vivitar Ring flash, and a Focal M500C for example.
Apart from the desirability of moving this stuff into its correct place (and I suppose ordinary users don't have the ability to do so), I wonder if it makes sense to separate the non-Pentax kit into current and legacy. Things are always moving on and todays models soon become legacy. It does not help that legacy equipment is grouped on the review index pages a long way down from the current equivalent, seen for example in
Pentax Accessories - Flashes, Tripods, Grips - Pentax Camera Accessory Review Database .
I eventually bought a Sunpak 544 and have put a review in the correct Legacy Flash area, so it is sadly separate from its close brother the 555 in the current equipment area.
