With a quick search I have found digitised historic Ordnance Survey maps at the NLS, here is the link to the latest available (1967) edition:

I have not found any reference on the map to a formal airfield, so in all likelihood it was just a farm field.
By navigating the site on the link you can load adjacent sheets, if you have the rough idea of where it should be and is not on the sheet I linked.
Edit: This sheet from 1947 might be better, the field adjacent to Viables Cottages looks to be the right shape & dimensions:
