What would model be if the front loader side is mf32 and backhoe side is mf52?

Hi,

I have a 1972 MF loader/backhoe that is designated as a model MF 20/40 on the rollover cage. It has a model 52 backhoe attached, and has (I believe) a model 32 loader attached. I believe my unit is an MF 20 industrial model. It's got a 3 cyl perkins diesel.
