Old hospital items

As I was leaving colchester general hospital
I noticed the display cabinet.
The little round flat box interested me as it was made in Allen and Handburys a drugs company. I worked for the company for a number of years ,and I had my photo in the Lanset paper for Drs. Advertising the new peak flow meter. That measures the amount of air taken down into the lungs.
They thought I would be good as I am an Asthmatic. The company was in Bethnal Green London. It was taken over by BDH drug company.
Allen and Handburys was the only office I ever worked for that had a doctors on site so if you had been off sick or felt ill while at work you saw them. Seemed a good idea.
Long time ago I was 18 with long blond hair right down my back,hot pants,mini skirts.
But the first time round. Those were the days 1970's chick !!!
