The following data contains an element of speculation at this present point in time.

The road numbers indicated have not been disambiguated as yet, and so may point to a more recent incarnation of that number.

It seems plausible that the first 7 numbers were all issued on the first known date for changes to the road numbers in Scotland, ie 16th May 1924. They work north then west through Zone 8 in a fairly logical manner. However, the next two while superficially in the same batch as A865/6, require a bit of to-and fro in the Western Isles, suggesting that they came subsequently. It will also be noted that had the A865 and A867 been allocated at the same time, then surely the A865 would have been the direct spine-road, with the A867 taking the long way around on North Uist.
c1925 A867Lochmaddy - Clachan B892 (part)
A868Branch to Tarbert Pier B898
The following 3 numbers were all allocated to the Isle of Colonsay, and so were surely allocated at the same time.
c1926 A869Scalasaig - Garvard -
A870Scalasaig - Colonsay House -
A871Scalasaig - Kiloran -
It is possible that the Corran Ferry Spur was allocated a number at the same time as the Colonsay Roads, and working south and east from there the numbers up to A875 could be considered part of this group. This would appear to be the only example of numbers being allocated towards Glasgow rather than away from it.
c1926 A872Branch to Corran Ferry -
A873Port of Menteith - Thornhill - Blair Drummond B825
A874Short Link at Balloch -
A875Alderpark - Keoculloch -
The A876 number was allocated to the Great Western Road route out of Glasgow. It is marked as under construction on a 1924 map extract, and known to have been opened in 1927. This fairly accurately dates the A876, and as the A878 was created seemingly as part of the same project, the next 3 numbers seem to have all been allocated together.
1927 A876Glasgow - Anniesland (New City Road (part), Great Western Road) B810
A877Link in Renfrew -
A878Link at Old Kilpatrick A810
The A879 could have been allocated with the above batch, or with the subsequent numbers, which work west then north to Caithness with the A882.
c1928 A879Glasgow - Bardowie Station B812
A880Ardentinny Ferry - Strone - Rashfield B834
A881Broadford - Elgol -
A882Wick - Duncansby - Thurso B875, B876
We return to the central belt for the A883, then again head north west to the A884. However, returning south for the A885 seems unlikely if, as seems probable, road numbers were given out sequentially.
c1929 A883Camelon - Denny B818 (part) on 1930 map
A884Carnoch - Lochaline B849
The next four numbers could again be considered as forming a single batch, working north out to Barra. However, doubling back to the A889, which is south of the A887 seems unlikely, so the A889 and A890 probably came later
c1930 A885Dunoon - Sandbank B835
A886Strachur - Kilfinan - Tighnabruaich B837
A887Invermoriston - Cluanie Bridge Inn B852
A888Barra -
c1931 A889Dalwhinnie - Laggan B848
A890Kirkton - Lochcarron - Achnasheen B855
The next six numbers can be considered as a single batch once more, working northwards from the central belt to Caithness. However, the A897 seems to have come a little later as it is not marked on the 1932 map, while the A895 is.
c1932 A891Junction with A803 near Antermony Loch - Lennoxtown - Strathblane B821
A892Callander - Dunmore Fort B828
A894Skiag Bridge - Laxford Bridge -
A895Latheron - Thurso B873 on 1932 map
A896Wick Town - Wick Harbour B874
c1933 A897Helmsdale - Melvich B872 not on 1932 map
The last two numbers are a little of an enigma. The A898 does not appear on any mapping or records so far discovered until the opening of the Erskine Bridge in 1970, while the A899 is clearly marked on maps dating back to 1946. Perhaps there is a short-lived A898 yet to be found, or perhaps the number was missed by the use of the A899 for the bypassed section of A8 prior to some of the routes above.
