Building a Standards Converter

[Neutron]

Now I have attachment privileges, here's a spreadsheet with my version of Frank's Hedghog parts list with my choices of suppliers and stock numbers.

I've probably made my own typos, so please check it and let me know if you spot any. Any remaining errors are my own fault.

There may well be savings to be made from cheaper sources for the more expensive or numerous components, but I wanted to make it easier and minimise the number of different suppliers.
