The first is for an insert barrel for the 100mm tank guns vz.53 (T-55) and D10-T6 (D10-T25).
The designation is 20-PSv-38
 
20-PSv-38 is the older variant designation. This round is designated 20-JPNhSv-38.
The original subcaliber ammunition was manufactured from German projectiles and cases and some czech made cases were manufactured too.
Joes round is new manufacture batch from the 70's.
It was used in the tank guns and self propelled gun vz.44. The gun vz.53 is a towed gun which did not use the subcaliber 20mm barrel.

The other items were not regular army issue.

@Nabob

Thanks for the correction. Unfortunately, I have very little information on Czech ammunition.
Is this a 20-PSv-38?

Rigby,

Thanks
 
The case are german. I can't tell with this bullet, no stamps on it. Maybe Nabob knows more.

I have added to the downloads section a pdf file containing a summary of my data on czech 20 mm ammunition for insert barrels. Waits for the moderators approval.
Please let me know if you have any further questions and especialy if you find any mistakes. Your specimen cartridges would also be nice to see and to compare it with my findings.
Please note that it was done in a hurry between cooking lunch and homeschooling my kids. So there is a possibility of unfinished sentences :)
