Recently, I managed to find an interesting rabit hole when searching up the Pz 38(t), as it had dozens of radical variants. From the traditional 38(t) Ausf. A, the Marder 1 H, to an amphibious boat/tank, I wish to show everyone these to increase the chance of one showing up on the front page.
Now, I'm only going to include ones of interest, as there are quite a few to see, so seeing the rest will be up to you.
(Also, pics are clicky clicks)

Now, lets start off with the "traditional" Panzerkampfwagen 38(Tschechoslowakei)

Everyone should know of this little piece of Czech machinery, being pressed in the Heer after Czechoslovakia was annexed by Germany. It became the base for pretty much every tank that's being shown below.

The 7.5 cm Sturmkanone Panzer 38(t)

This is an interesting attempt to turn an outdated chassis into a capiable tank destroyer. Mounting a StuK 40 7.5 cm gun on an open cockpit, much like the Marder series built off the same chassis.

My favorite of them all
The Panzer 38(t) Ausf. A mit Schwimmkörper

This, from what I could tell, was a failed first attempt to make an amphibious tank for Operation Sealion(Like the Sherman DD and Valentine DD). There was a version of this, the biggest differance was it being a Panzer 2.
Also, something very similar to this

The Flammpanzer 38(t) Hetzer

Basically a Hetzer, but with a flammenwerfer instead of a whatever-mm-gun.

The Vollkettenaufklarer 38D

It is unknkwn what exactly what this variant of the 38(t) would of served as, but with an educated guess, it would of been either a tracked APC or Munition carrier (not like they didn't have 3-4 variants already).

The Aufklärer auf Fgst Panzer 38(t) mit 7.5 cm KwK 38

The Aufklärer, another attempt to make the outdated chassis into an up-to-date tank destroyer to combat increasing enemy tanks. I say, unlike the Sd.Kfz 234/4, never got past the prototype stage.

Anyways, that would be a list of some interesting variants of the Pz 38(t).
And before you yell about the Wespe, Grille, or Flakpanzer...
You already know of those, and they aren't too rare to hear of in WW2 discussions.
Anyways again, enjoy this small grouping of tanks, and lets hope you've been inspired.
