Good news, Rodinal and Rodinal Special is back in stock in Gunns from next Saturday
Casting my mind back to the late seventies/early 80's, I think Rodinal Special was put out as a way of getting more mileage out of an existing product, ie Studional, which was the liquid fine grain deep tank developer in the Agfa range. Selling it as a small tank FG developer related to the true Rodinal might have had some tenuous connection with the US practice of adding sulphite to Rodinal for finer grain. For most of the 80's & 90's it wasn't available in the UK as Agfa GB didn't import it, but being in 125ml it has (when available in the UK) fitted the same niche as Ilfosol or LC29, being handy for the occasional user.

Three cheers for Rodinal Special / Studional. Same stuff, of course, different bottles.
Increase the dilution: 1+31 or so. Wonderful.
