NaPTAN lists the name as "The Yenton", the Street as "SUTTON RD", and
the Indicator as "Stop YF"
Currently, the converter pulls these out as name=The Yenton and ref=YF
Incidentally, this stop does have a NaptanCode of nwmdgpgm, but I
cannot find 504974 anywhere in the database. (Nor 504956, as shown in
the photo).

Only the reference (YF) is listed in NaPTAN.

Yes, this is common on all London bus stops that I've seen, its not in
Naptan though.
(Incidentally, the two Holly Lane stops are almost identical except
for the codes, Indicator, opp vs adj, and Bearing, NE vs SW.)
