"Normal" equivalents of the 10cm KK and 4.7cm FestungspaK, and anything about the le. H.T. (10.5-cm L / 14)?

I know that the R663a and 663b bunkers were armed with the 10cm KK, and that there were plenty of Regelbau designs that used the 4.7 cm FestungspaK 36(t), and that the R664 "emplacement for light howitzer in a turret" (although looking at the mounting it's so high angle that it's effectively a heavy mortar) was armed with the "high speed fire gun" le. H.T. (10.5-cm L / 14) Essentially, I'm wondering what the "normal" equivalents of those guns were, and trying to find out just about anything at all on the 10cm KK or the le. H.T. (10.5-cm L / 14); for the former I've only been able a mention of it in a list of guns a particular shell can fire, and a name of "mittlere 10 cm Kanone Kasemate und Turm" that -might- suggest that the le. H.T. might be a cut-down 10cm KK. For the le. H.T. (10.5-cm L / 14) I haven't been able to find anything.
I'm assuming that the 10cm KK and the FestungspaK guns themselves were not completely unique, "clean sheet of paper" designs, but rather existing guns modified to fit on new mounts, possibly with a shortened barrel in the case of the howitzers. I'd assume the 10cm KK are modified versions of an existing "normal" gun/howitzer on a special mount, and that the 4.7 cm FestungspaK is an adapted version of an existing "normal" Czech antitank/tank gun. What I've been completely unable to find is what guns those were. For the le. H.T. (10.5-cm L / 14), I have absolutely no idea what it is, google translate's "high speed gun" suggests it's some highly unique fortress gun, but I haven't be able to find out what it actually is. Does anybody happen to know what the KK and the FestungspaK were adopted from (or if they were unique designs), and does anyone happen to have just about any information on the le. H.T. (10.5-cm L / 14)?

Thanks.

Also: google translate's "The use of le. H.T. (10.5-cm L / 14) was basically train-wise, this meant that there were always 2 stands..." - I suppose that mean the mount has limited traverse?

The 10 cm Kanone was developed as anti-tank gun, for the use in armoured casemates or revolving turrets. That's what the "Kasemate und Turm" refers to.

I don't know how the 4,7 cm Pak K (t) was developed, but the fortress weapon 4cm kanón vz. 36 and the mobile gun 47 mm kanon P.U.V.vz.36 seem to share performance characteristics (at least according to Wikipedia).

I think all these gun were especially designed for fortification and were not copied from existing guns .
Can't speak for the 4.7 cm PaK K.36 (t) because I don't know his background .

For the 10 cm K.K. there were - or planned three versions
Kz. 10 cm K.K. L.26
M. 10 cm K.K. L 30.9
Lg. 10 cm K.K. L 72 ?

For the le.H.T. 10.5 cm L/14, the rounds from this gun are more like for a mortar .
The reach of this H.T. kanone was 300 m. till 6000 m. with 360 d.

Czechoslovak fortress gun Mk. 36 calibre 47 mm (marked 4,7 cm Pak K (t) in German hands) originated in the Škoda naval gun, which was in developement for the Iranian navy at the half of thirties.

Czechoslovak field antitank gun Mk. 38 was developed two years later, using some parts of the fortress gun.
