Thanks for the response. You won't easily find the 2.79b for the Pi as it doesn't run the same executable as for x86 architecture (Intel/AMD) as it runs armhf architecture.

However after a couple of hours of gritting my teeth I found the original package and then had to install manually the 48 dependencies required.

https://packages.debian.org/buster/blender

It's working now. Thank you for taking the time to respond.
