Hi,
You're not nit-picking. But nor are you correct.
There was an F2 variant and it was different from the G model.
The initial F model (Chassis numbers 82001 to 82614) were built from April 1941 to March 1942 - a total of 462 were produced, and 25 were converted to F2 models.
The F2 (chassis numbers 82370 to 82650) were built from March to July 1942 - a total of 175 were produced, including the aforementioned 25 conversions from the initial F model.
The initial F model could not combat the Russian KV-1 and T-34 AFV and an order was issued to mount the KwK40 L/43 gun on the F model. This caused a month's loss of production in March 1942, and the F series was completed with the L/43 and was designated Aus F2.
Differences between the F and F2 was largely, but not completely, due to the larger gun. Ammunition storage was modified to house the larger shells, and the gunners and commanders seats were changed to allow for more room. The elevation mechanism was modified and an auxilliary hand traverse was installed. Because of the long barrel, a coil-spring counter balance was installed for the L/43. The hull rear armour went from 20mm @ 9degrees slope on the F to 20mm with 0 degrees slope on the F2.
The G model (chassis numbers 82651 to 84400) were produced from May 1942 to June 1943 - a total of1,687 being produced. Actually, 1,750 were made, but only 1,687 were built as G models, as 10 chassis were used for the Hummel (Bumble Bee) and 53 chassis were used for the Brummbar (Grizzly bear).
From late March 1943 the KwK40 L/48 was installed, instead of the L/43 - with a total of 1,275 G models (out of 1,687) having the L/43. G models with extra armour, bolted or welded on, began on 20th June 1942.
The G model had vision ports eliminated in the turret sides and in the loader's side of the turret front. The hull rear was 20mm @ 9 degrees slope. In the summer of 1942 changes included a new style of muzzle brake, as well as installing a system that allowed the transfer of coolant from to another MkIV to aid cold weather starting. Smoke discharges were installed on the turret side instead of on the hull. In January 1943 the drivers episcope (KFF2) was eliminated. Schurzen were added in 1943. The very late G models got a new type of drive sprocket and the radio antenna was moved to the left hull rear, making it almost impossible to distinguish a late G model to an early H model.
Model F2
weight - 23 tons
length - 5.62 metres
width - 2.84 metres
height - 2.68 metres
range - 200km
Model G
weight - 23.5 tons
length - 6.62 metres
width - 2.88 metres
height - 2.68 metres
range - 210km
So, the F2 is a distinct variant of the MkIV. Sure, it may be very close to the G version, but it was different enough to warrant the F2 designation, and I have yet to read any text that says there was no F2, and they were all G models.
