Hello everyone!
I know it's been a while! After asking for your help, I have been taking my time to
figure things out and try everything to make this model.

Attached is what I managed to do. Thank you so much for all the advise.
I cheated in some bits and improvised in others. It has definitely been a learning curve.

I know it's not perfect, but I will keep at it! Your comments are welcome!
Cheers.

Sandeep.
