FS: Chassis Engineering Centerlock, 6 Pin Drive Wheels, 15x10 & 12

I got these in a Porsche parts lot purchase out of a Porsche race shop, so I am hoping not only are they Porsche, but someone here might know exactly what they fit.  

Set of four wheels - look like they have never been used.  They are 6 pin in a 3.5" diameter circle, and the pins look to be 3/8" diameter holes on the back, and 5/8" on the front side.  They are Chassis Engineering Brand, popular in Can Am, formula car, and all kinds of racing back in the 60s, 70s and 80s.  

Similar to Centerlines, obviously, but not that brand. they also have a non-ferrous (maybe Magnesium, just based on the fact it's darker than the aluminum) center disc in between the inner and outer halves (I have an identical set of Porsche fitment wheels from the same purchase).

15x10 - 3 1/16" backspacing  16.0 lbs
15x12 - 3 1/16" backspacing  17.4 lbs

Fitment could be Lola March Indylights, Lotus 23/51 (but too wide for that), FSAE, ??  Appreciate any input that might nail it down for sure.  Cast pin hubs unbolt from centers, so could be removed and redrilled for another application, of course.  

$1000

Still have these.  Looks liek they are going to turn into end tables....

Still available - willing to take a lower offer to get the space back.  

Those would be perfect for my Lemons car, just need to adapt four lug to six lug knock off.

These seem to be an odd construction, like two bowls bolted bottom to bottom. Is the pin drive piece just held in place by the three bolts? what's the black bit I can see between the two bowls? I'm looking for ways to fabricate some 10-12" wide wheels for my Challenge car, so this stuff looks interesting.

Yes, 2 piece construction, just like Centerline wheels.  As I mention, the center darker piece sandwiched in between the aluminum halfes is something I don't know.  I suspect it is magnesium, but not sure.  

The 6 pin hub is held through the centers with those 3 aircraft bolts.  The 6 pin holes do go all the way through the entire wheel, but I'm no expert on centerlock construction!

I toyed with the idea of removing the 6 pin hub and redrilling the centers for something else, but it would have to be just right in terms of size and hole location

The pins only hold it in place while the center nut is run down; I have some Compomotive Turbos of similar construction. These are very cool!

Bump

So I got tired of seeing these things just sitting there, so I got some threaded rod and washers and nuts, and bolted one 15x10 and one 15x12 to each other.  

Presto - instant seats or end tables.  Depending on if I put glass tops on them, or cushioned seats.  Or maybe vintage drink trays.  We'll see.
