Dimensions of available springs and where to get them

[evert]

We have the spring dimension thread, that lists everything people have measured.
But I suddenly had the idea that a thread listning available springs and where they can be bought would be a good resource.
Remember that spring sizes changes with batches and scragging - and measurements can be approximate!

So, I'll fill in what surfaces of updated info here:

Maccari/Air rifle headquarters
Maccaris selection changes over time as he adds new springs. He also sometimes makes changes/tweaks to his springs over time.
Info can be found on some springs on the website some of the springs here are measured by me.
Some of Maccaris springs have closed coils in one end to give extra piston weight.
