TA crankset identification - help!
 

Need help figuring out what this TA crankset is.

Looks like a mix between a TA Cycletouriste and a Randonneur

Looks like it has the 50.4mm bcd (5 "arm") crank arm attachment

The inner (smallest) ring seems to be on the 80mm bcd holes attached to the outer ring...

But the middle chrainring appears to be not on the 80 bcd holes but something larger... 122mm bcd maybe?

I didn't know there was such a configuration. As I thought on the Cycetouriste all the rings sat on one bolt hole.
I guess the big chainring looks like a Stronglight model 49 ring, but it has the 80mm bcd holes to attach the small inner.

Any idea of what I have here? Thanks in advance!

I can't tell from the pic, maybe you have the double adapteur that's been drilled for the granny ring? That would be a Criterium/Professional I believe

Yeah, I think you're right on that.. Looks like the Professional with the double adaptor.

Hmm, so, somehow it got drilled out for the triple.

Not sure I need this, but If anyone would like to buy it, I'm open to offers. I know I could get at least $50 off Ebay for just the arms...

Yeah, I think you've got the "adapteur" that's been drilled in the cyclotouriste pattern.

I have an old Lambert ring drilled like that:

Are there any markings on the arms?

Looks like poo. Send it to me. I have plenty of Charmin. :D
