Ok....
 

Seems quite possible - any comment on Skippy saying "rippled"?

(and should I expect the word along the back leg seam - or were there
several designs for Endurance briefs* over the years?)

*I mean brief as in brief swimsuit - I have to remember that in the US
briefs are underpants, and have been caught out many times on that in researching small speedos.
(I can clearly see that these have Thai cords of course)

it's an Ebay purchase -- you have to expect that about half of items sold are what they describe. You have a 50/50 chance of getting a real deal which gives you an equal chance of getting screwed.

Well 2" side endurance suits do exist and they are listed as endurance 5cm suits and Hopefully I can purchase a legit one on ebay for a good price.

The Speedo Endurance 5cm does exist in UK, but only if you are size 30" (navy), or size 40" (black)
Enjoy the frustration .....
