Delahaye questions (the classic car)

What do the different designations mean; i.e. 135, 135M, 165, 175, etc?

Were they all built on the same basic chassis (within certain year groups)?

I’m wondering because I want to find a scale model and modify the body into other coachbuilder’s versions. I want the chassis to be correct…or at least the correct track and wheelbase.

OMG Figoni and Falaschi Delahayes were the most beatiful cars ever!

Thank you
