Silly little pipe on MC intake manifold?

Very interesting, I have this drain pipe, along with the retaining rim
around the intake manifold. The car was built in 5-88 BTW, and has a K26
turbo, along with the one piece exhaust, and single knock sensor....
Is there a chance this is really an MC2, not an MC1? I bought it assuming it
must be an MC1 with the turbo it had on there, and single knock sensor,
along with the MAC 11 ECU.....
Thanks
