The 1920s/30s Infantry Division did look rather like its WW1 counterpart. Three infantry brigades of three battalions, and artillery 'brigade' with 18pdr and 4.5" howitzers plus divisional sappers, signals and recce.
The infantry battalions until the mid 1920s still had BHQ, AA Platoon with four Lewis guns and four rifle companies on the WW1 organisation (four platoons of four sections with two Lewis guns per platoon). The Brigade MG companies seem to have been devolved back to the infantry though as each battalion had an MG platoon with six Vickers guns.
The absence of a battalion mortar platoon indicates that the brigade 3" mortar company was retained.
At some point in the late 1920s, battalions dropped to three companies until the four company org was reinstated in 1936. The Vickers guns vanished back into the divisional MG battalion at some point too.
No idea about any AT gun allocations, but in the 'Defence of Bowler Bridge', the platoon defending the village was allocated a single 20mm AT gun with a tracked carrier which they engaged the enemy armoured cars with.
1920s/30s cavalry regiment was similar to a WW1 type, RHQ with a regimental Vickers platoon (4 guns) and three squadrons of four troops, each with a single Hotchkiss LMG.
