some news on EFP70T last taxed Sept 1988 (was due October 1st)
not SORNed of course because it is untaxed before the rules started (may have been 1995)
but....... change of V5C details March 2020, so it looks to be still around, which surprises me as the bike hasn't been taxed for 32 years! and in 1988 there were still quite a few being raced and trashed, not as many as four years earlier, but never the less it would seem to exist, you never know though, this could be just a paperwork thing, maybe the current owner will see this.
Another good place to try a "where is it know" search is in The Old Bike Mart.
