Have a friend in Okla. who is an Alfa fan.   Has the same problems today, keeping it running.   The Sunbeam was a really quick car for its day.    Saw a couple that had the Ford V8 in them modified for a bit more even. Only car I ever saw that had little lens covers that would pull down over some dash lights for night driving, reduce the brightness, thought it was neat.   
I had Austin Healeys and Lotus same time you had the Alfa and Sunbean.   Great cars all, great fun.   We always flashed our lights at other sports cars when driving as a way to say Hi.      Not done anymore.  I still have my "Dan Gurney for Preident"  sign.      Aw those were the days.
