Vintage 1969 Mattel Sea Devils Rick Riley and Chuck Carter plus equipment

Description

Vintage 1969 Mattel Sea Devils Rick Riley and Chuck Carter plus equipment.  Condition is "Used".  Shipping is via USPS Priority Mail.
I was a child of the sixties and fortunate to have Major Matt Mason, Hot Wheels, and the original GI Joe.
For me, these guys were good since they were the same size as Major Matt Mason, but not nearly as interesting.
The advantage of that is that I didn't play with them much, so the condition of the two figures is quite good.
These have always been in a smoke free environment, but were stored for a couple decades in a Minnesota attic.
As such they were exposed to cold winters and hot  summers.  The two figures came through fine, but their two vehicles
(I think called the AQUALANDER and a SEA JET)
have some "melt damage" from resting next to other items.  I tried to highlight the worst of the "melting" damage in the final two pictures.
Both figures have complete, unbroken, wires within.  The fellow in orange has a small mark on the right side of his face (picture 5) but overall, the faces for both guys are great (see pictures 5 & 6).
I think originally there may have been black hoses to connect their air tanks with their helmets.  Those are gone. I do have the blue air bladders and longer black hoses though, as shown in picture 10.  I'm not sure how these were used unless it was to generate air bubbles under water.  These hoses are quite supple.
One helmet has it's visor/face-plate but
one helmet is missing the visor/face-plate.
Missing one orange flipper
.  If I happen to find it, I will mail it to the winning bidder via USPS mail.
The insides of the two white and orange propeller units seem clean but
I could not get them to function when I put a battery inside.
Please examine the pictures for condition and contact me with any questions or concerns.
These items will fit within a mediumn flat-rate USPS Priority box and that's my plan for shipping it.  However, if the winning bidder prefers another shipping method, I am willing to discuss that.  Also, if the winning bidder is the winning bidder of other auctions (I mainly have some of my old GI Joe stuff up this week) I will combine shipping however possible.
