What's up with these suits I bought on ebay

[Torchwatch]

A very long time ago, Speedo did use their swoosh without the "Speedo" text but I suspect we are going back to the days of nylon suits, it was on a glued on printed "badge" that could flake off. A modern suit should have the Speedo swoosh and "Speedo" text logos embroidered on.
These could possibly be very old suits that have been in storage, the elastane content of the Lycra may have corrupted, put them on and if the crotch drops towards your knees they are corrupt.
To counter the above argument I don't think the Endurance product is that old, having only been available in Europe for a few years. The Endurance effect is to make the suit last longer, ie to stop the crotch dropping down to your knees. This creates a paradox of a modern Endurance suit in storage for a long time, longer than Endurance have existed perhaps.
One of the suit labels says "Fabrique en Chine", this is French for "Made in China", this label was intended for the European market but ended up on a suit that got onto Ebay USA. Speedo were making suits for Europe in Sri Lanka before they contracted to have them made in China, if they are old suits then the labels don't match the suits.
The factories that own the RN (registration numbers) are contracted to make garments for the International Brands. See photo of an RN and bar code label earlier in this discussion. These factories often take on more work than they can cope with and subcontract it out to less reputable sweat shops. The sweat shops take possession of all the labels including the RN. From this source surplus genuine labels can get onto the fake market.
For about £60 or $100 anyone can set up in silk screen printing, you could print anything you wanted onto any old suit and make it more interesting. Who wouldn't want "Speedo" across the back of a suit, and the "Endurance" logo is desirable.
I suspect but cannot prove that your 2 suits have been made from old fabric, have old style swoosh label badges, genuine but misappropriated labels and some dodgy silk screen printing, and that similar suits are available throughout USA.
Fake goods do not satisfy peoples expectations and might put swimmers off the Speedo brand for life.
