Pfaff 145 questions

[Cheval]

I actually did come across Mark’s website before, am checking in again with him.

Any idea on how the 145’s differed between the leather and non leather numbering/lettering and heavy vs light duty? I have a CLMN P,  would the non leather version just have a less heavy foot/needle setup and the bones of the machine are the same?

To my best knowledge:

• C: Needle plate hole 2.2mm
• L: for leather Leather
• M: don´t know
• N: max stitch length 6 mm.
• P: Special Equipment / Application (maybe pneumatic support or the like)

I wrote it down once but don´t recall the source. I´m sure someone has a more complete subclass list.
