I believe it was a T84A, short wing with no lower ribs. Bought it early in 85 had been with the dealer for some time, rotax 377.  

I’ll take your word for it - there were bugger all 84s built. 
 

I only knew of the t84 with the longer wing and the earlier riveted tail group - that one has the later bolted into threaded insert aluminium tail group and short wings but as you say clearly no under battons.
