Extracting DATES partial or full from text

Hello,

Had a look around to solve this one but all formulas I've tried don't seem to work for my data.

Just need to remove the date part of the text in col A, and really just need the date range extracting (I can split the dates once out of the main text) As its just a Month and Year in most cases, some only have a start date (vehicle still in production) some have a start and end date.

Help please!!

Thank you
Matt
