Thanks very much. That’s a generous offer. If you do find time to check, I’d be grateful. I’ve narrowed it down to eight issues that aren’t in the archive.org scans. My submission was mentioned near the end of Wilf’s column, just before the usual sign-off and the postal address in Bath.

(You might meet PaulRobinson while you're there, looking for the same issues!)

Thanks again for even considering it. Much appreciated! My email address is my HN username at gmail.
