Edgar Sealey changed their logo twice before closing for business in the late Sixties, I'm afraid. Having branded their rods as Octofloat for some time, with a green octopus logo, they carried on with the name but dropped the logo for two intertwined fish, later stylised in a more modern style just before the end came.
Like most companies, they were experimenting with fibreglass as well as carrying on with cane, so some of their rods appear with either logo, in cane or 'glass and even a mixture of the two.
They made the Octofloat, with white ceramic lined tip and butt rings, the Octofloat Deluxe with those rings replaced with agate lined ones and a reel holder of two rings on a floating tube ( I like it, many don't, ....but we all agree it is ruddy cold in winter) and then the Octofloat 2 in pale brown, un gelled fibreglass. Once the gel-coat technology was established they did a number of match rods such as the Blue Arrow, Black Arrow and Featherlight rods.
I have heard of unscrupulous restorers with access to laser jet printers making up labels for highly prized rods, but I think an Octofloat is below their target victims, I'm afraid.
If the rod is for re-sale, I'd leave it with whatever is left on it, if it's for you to use then it is for you to choose. Not a bad rod, and fetching more money of late than for many a year. If you are trying to re-whip it in original silk, you may go to your grave before you find the right red/green jasper ...I thought I'd found some but the ratio between the two colours was wrong.
