Best way to put DIL pins on a small PCB to create replacement for old parts.

Indeed , I think that is the way to go to ensure that no damage is done to vintage sockets. The lead frame pins seem to be around 0.25mm which is perfect. Now to hunt them down at a reasonable price! I've sent a query to Batten and Allen about their BA3760 pins that were mentioned in the top of this thread - I suspect MOQ will be a killer though.

These are what I get, for a bit more than US$0.04/pin (incl. 19% VAT) at the current exchange rate. The pins are 0.5mm in diameter to plug into IC sockets. Perhaps an order might be worthwhile if Reichelt ship to Oz and have other things you need.

I tried lead frame pins and I found them difficult to work with. You can get cu-to-length on Mouser I think. I might be able to search my archives for the part. I ended up using "arduino headers". They are almost as thick as the flip pins though I think.

They are (were?) widely available. You need to screen out all the square pin variations that will come up in a web search.

Ok yeah - looks like those are 0.64mm square pins - unfortunately those will destroy the sockets I'm working with. I need to find something around 0.3mm to 0.4mm max I think.

They are not square, I know you are trying to avoid that and so am I. They are flat and look like this:
