But of course as 25-pounder became available many of the 75mm were re-issued, first to the 'Home Counties' brigades and later divisions and then to the Home Guard. However, a fair number of them may have been shipped to Egypt, since the 75mm shows up there in the Western Desert as well. I'll check but I believe some arrived there as early as November or December of 1940, evidently coming from England?
The point is that they only needed to be a stopgap to fill the minor shortfall between new production of 25-pounders and the losses sustained in France. Thanks for the reminder about Nigel's wonderful site, we know that the numbers of artillery in the UK as of the end of May 1940 were:
126 18-pdr
269 18/25-pdr
90 25-pdr +252 produced June-September = 342
So 737 total field guns, sufficient for 30 regiments with a small reserve of 17 pieces. That's enough to fully equip 10 divisions. Now a quick check shows there were just 17 regular regiments in the UK at that time, plus 5 RHA, while there were 82 TA, so 104 regiments to be equipped and a requirement for 2,496 pieces in total. That of course amounts a minimal shortfall of about 864 guns to WE, even if we add in the 895 US guns.
Rich, you have mis-calculated the 25 pdr production, there were also 299 of the 18 pdrs converted to 25 pdrs, + new 18 pdr production. There were 638 of 18 or 25 pdrs produced June - Aug,
not 252.
Also the 4.5" howitzer (114mm) and the 60 pdr (127mm) were used as field artillery, not medium.

Eight 6" Medium Howitzers.
Two Field Regiments - 25 Pdr. 4.5" How. and 75 mm.
Eight 12 Pdr Guns on Lorries.
......
So the situation looks far better, with all artillery regiments up to strength by mid-Aug (although not all with 18 or 25 pdrs)
By Aug 16 1940 (3 days after "Alder Tag") the British will have produced about 82% of the 1285 guns listed on the link, giving a total of 2,466 field artillery from 75mm - 127mm.
831 - 25pdrs = 359 initial + 472 produced
177 - 18pdrs = 126 initial + 51 produced
895 - US 75mm,
451 - 4.5" howitzers 321 initial + 130 produced
112 - 60 pdrs - 14 initial + 98 produced
They probably have 100 - 150 WWI era guns as well, 13 or 12 pdrs (76mm), which were brought out of storage in the summer of 1940.
On Aug 16 the British forces might look like this:
17 regular regiments, each with (3 x 25pdr batteries)
5 regiments RHA, each with (3 x 25pdr batteries)
82 Territorial regiments
10 territorial regiments each with (3 x 25pdr battery)
4 territorial regiments each with (1 x 4.5" how battery + 2 x 25pdr battery*) - (*1 battery is short 1 gun)
11 territorial regiments each with (1 x 4.5" how battery + 2 x 18pdr battery)
41 territorial regiments each with (1 x 4.5" how battery + 2 x 75mm battery)
14 territorial regiments each with (1 x 60 pdr battery + 2 x 75mm battery)
2 territorial regiments each with (1 x 75mm battery* + 2 x 13pdr battery) (*1 battery is short 1 gun)
Total used:
831 - 25 pdr
176 - 18 pdr
448 - 4.5" how
112 - 60 pdr
895 - US 75mm
32 - 13 pdr
There were something like 27 medium regiments formed, so a requirement for 432 pieces. The 434 available were just sufficient, especially when the production of June-September is added in.
321 4.5-inch howitzer
14 60-pdr guns (being converted to 4.5-inch)
5 4.5-inch/60-pdr guns (converted)
94 6-inch howitzer.
By mid August there would be 23 medium regiments:
26 - 4,5" gun = 5 initial + 21 produced
302 - 6" how = 94 initial + 208 produced
42 - 6" gun = 0 initial + 42 produced (I'm assuming that the 20 initial in UK are all static mounts)
Total = 23
18 medium regiments each with (16 x 6" how)
1 medium regiment with (14 x 6" how)
1 medium regiment with (16 x 4.5" gun)
1 medium regiment with (8 x 4.5" gun + 8 x 6" gun)
2 medium regiments each with (16 x 6" gun)
By the end of August there would be enough 4.5" guns & 6" howitzers to make 27 medium regiments.
