Sounds very much like a Tipo +.

The canopy was moved back a little, the wing was straight trailing edge, but you could order the standard double taper wing, the stab was thinner, flat and slightly lower (3/4"?), or you could order the standard thick anhedral stab.

I personally flew the Tipo+ with the original wing, but new stab. I bought and built these in the 87-88 seasons.
