I have only just come across your layout.
A most interesting and unusual subject.
Your models are superb and, I am sure a great source of satisfaction.
Glad to hear you survived 35 years of the NHS - my own experiences varied between NHS, University, NHS, retirement on health grounds, NHS, University and lastly NHS - not so much a career, more a series of errors and/or omissions!
Keep up the good work and I hope you fine a permanent home
Best
