There also always was (still is?) the Derbyshire wayfarer-similar, but a bit more southerly, also for train&bus, incl to/fro Sheffield.
As there is for rangers and rovers on trains, such a complete list for bus-day-tickets for the UK?
Myself from Nederland and in the past often visited the UK, also for bus-interest.
Here in NL we once had in times fo that strippenkaart a national dayticket, but now its either operator or regional, with very good or acceptable offers. In Dutch they are listed on the site of rover.nl (publ. transpo users organisation), but not yet updated for 2019. Look for ''op reis'' ''dagkaarten''.
On the site of 9292.nl- national travelplanner for all means, there is also very hidden a listing.
