On the maps I have it's labelled Princes St.
On StreetView it looks like the end wall of number 24 has been rebuilt, the continuation of the terrace having been demolished. The houses around look like they were built in the 1970s or 1980s.
From the spacing I would have expected Princes St to reach Milton Rd, and the 1937 map on
www.old-maps.co.uk shows it like that.
Since numbers 2-22 would have been the same type as 24 upwards, there must have been a reason other than "slum clearance" for the demolition. It's possible that the low numbers suffered the attention of the luftwaffe in WW2.
