I would like to suggest the 10,5 cm LeFH 18/40/2 (Sfl.) für Geschützwagen III/IV, which is the 3rd contendor and build by Alkett, it was the most simple of the 3, however also didnt really confirm to the requirements, resulting in it also not beeing build beyond the Prototypes, as the same hull was more needed in form of the Hummel 15 cm SPG, which offerend more potential than the 10,5 cm LeFH 18.

The idea behind the vehicles, where to have an mobile self propelled 10,5 cm LeFH, which could be fired from the vehicle or dismounted as a static or towed gun. For this reason it also had an hydraulic lifting framework that swung upright into position and could be used to lift up the turret and place it behind the hull, so that the hull itself could also be used as an ammo carrier. After a long development and worsening war situation with the ever growing need of materials and normal Pz IVs, it was decided to abandon the Waffenträger IVb as well as its other contendors and settle instead for the more cheaper Wespe.
With this vehicle not even fulfilling the requirements.

In game it would offer a solid fireing platform with a allready familiar vehicle and gun, beeing the 10,5 cm LeFH 18, as allready found on the StuH 42G in form of the StuH 42 L/28.
With this vehicle following more of a playstile like the Marder III Ausf.H than the other 2.

And this one still exists too.

What a funky SPG! +1

+1, never heard of it, it seems really cool

Clearly rotated Superstructure and not just the gun itself.

A +1 from me; fun fact: the sole surviving prototype is owned by the same guy who also owns the following (among others): three Tiger Is, two Tiger IIs, four Panthers, one Elefant, 10 M4 Shermans, two M10s, four Jagdpanzer 38(t)s (G13 conversions), a Bf-109D, a Ju-87G, and an S-Boat
