Can anyone near Basel CH lend me an M mount 135mm lens?

I’m working on a project, and can’t decide whether or not to buy a 135mm lens for my Leica M3. My GAS-fuelled brain tells me to just buy one, but I don’t want to end up with a dust collector that I rarely use (I have enough of these already).

I know it’s a big ask, but is anyone near Basel (Switzerland) willing to lend me an old 135mm lens for a few days so I can work out whether it’s a focal length that works for me?

Thanks in advance,
Ian

If you can't find find a loaner you can often rent lenses from the camera store.
