Maybe I am wrong, I have not noticed that images in CML 2.4 (or did I missed)

as per I know only the below images are available to use.

They are not images in CML. I found out from a Cisco employee that the 4300 series ISR router can be emulated with the CSR1000v (or Cat8Kv) in CML.  The 3900 ISR can be modeled with the IOSv node

yes IOL 15.7 L2 and L3  / IOSv L2 and L3  available so most of the command syntax same for that router.

CML is simulator, it will not exact as Physical hardware, most of the IOS / IOS-XR  and nexus functions can be used to emulate or simulate to testing purpose. some have limitrations that can be find in the feature documentations.
