the only recent RD named College was in Glasgow from 1935-1955. The table also says:
Old RD 644 7 (not sure what that 7 signifies)
Yes. The only RD named College was in the city of Glasgow. It was RD No 644.7 from 1935 until 1955.
The number assigned to Glasgow parish was 644. It was subdivided into a variety of RDs, each of which was given a separate sub-district number. These changed over time as the boundaries of the RDs were altered.
The whole thing was further complicated because the parish number for Barony was 622, and that for Govan was 646, and various RDs in the city were allocated numbers which were subdivisions of those rather than of 644.
All original parish and RD numbers were scrapped in 1971 and the districts and RDs were re-numbered from 1972.
So any event in College did not take place in Aberdeen.
Aberdeen city's number was 168, and there were various subdivisions of 168. Since 1972 Aberdeen's number has been 300, but sometimes, if there is a large number of events, it spills over into 301.
Rural parishes in the county of Aberdeen (aka Aberdeenshire) were numbered from 169 (Aberdour) to 249 (Udny) under the old system until 1971, but since they *****ed up local government areas in 1975 I have lost track of which RD numbers are now in Aberdeenshire - and that is further complicated because they gave the name Aberdeenshire to an area that now includes all of Kincardineshire and about a third of Banffshire as well as most of the proper county of Aberdeenshire.
Inverurie was RD No 204, but it is now No 319.
