Going through boxes, I found this photograph of my father, Malcolm Ottaway, working on the Cornell cycloton. He engineered and built the stand, which had to be mobile but very very stable. I suppose it is called something other than a stand, but he died in 2013 so I can’t ask him. The photo would be from 1964 or 1965.

I framed it. What was the excuse for not framing it before?

For the Ragtag Daily Prompt: excuse.
