Can't get 19d and 28 a.
19 Banger. I have ?in?
28 Nest in back garden. I have D?A?. Looks like drag ( reverse first letters of garden) but can't parse it.
It has to be NOBLE but what does the "Toff, 23, " bit mean? I assume it's T OFF rather than Toff and 23 is LATIN so that leaves LAIN, but I still can't see the connection.
