Industrial Generator Lead Times

Do any of you guys know what normal lead times used to be before the pandemic and supply chain issues killed them?

What was Caterpiller/Cummins/MTU/etc. delivering at in 2018? And is that a normal that is going to come back?

Do any of the players have shorter lead times than others?

We're doing some scheduling work and its like throwing a dart into a dark room for anything 1MW and above at the moment.

Given this is a room full of engineers, I figured you guys might have better guidance than distributors who seem to gave a "place the order and then we'll tell you" approach at the moment!

I'm seeing crazy numbers, like 18 months to 2 years in some cases!
