Perhaps I was applying a bit of poetic licence when I say I was involved with the building of the enginehouse. What actually happened was that by the time I became a volunteer the enginehouse was built and the Bellis and Morcom parked inside along with a large Robey oil engine that was installed properly and did run.
What our group did was clean and prime the "critall" windows. This took us 5 consecutive Sundays from 10.00am to sunset. January 1982 I think it was.
Then I think the money ran out as the glass was not fitted and there were no doors. This was the situation when I left 3 years later so it's possible that this is why the frost damage happened.
Certainly it was cold when we were working and we often had a tea break sitting on top of the B&M as it was just out of the wind that came through the open doors and windows!
I haven't been back to the Museum since, must save up for the entrance fee and have another look.
One thing's sure, I wish I was as fit today as I was then.
I must see if I've got any photos from that time. For those of you who never knew the pre-digital days photos were taken on film and taken to the local chemist for developing and printing.
