Intercooler identification help

[1984 t-type]

So I have what I assumed was a stock intercooler until I attempted to put new hoses on today. It is stock appearing and I don't see any marks where it would had been cut and welded like a Dutt neck intercooler, there is a marking on the turbo inlet neck and the inlet measures 2.5" take a look and let me know what you think. This car had a lot of old but good parts on it when I got it so I doubt it's anything current.

Thanks

Is it the stock length at 10 rows of tubes (top to bottom)?
I believe the stretched stock location I/C's started with 15 rows, some 17 and some double core (20 row).
