Technical Need help Identifying my 1929 Model A Roadster Pickup

Good morning Guys. I just purchased what I was told is a 1929 Model A Roadster Pickup. Needs A lot of Love but one of the books I have tells me that this model did not have door handles until 1930 so I really need help making sure that I order the right year parts. See Photos many thanks Tom Gormley i.e. Mercuryguy on this site

 

Looks like 1928/29 from where i'm sitting

 

Liberated this from Ford Barn:

"all open pickups 28-29 did not have outside door handles.
roadsters and phaetons did not have outside door handles until Oct/Nov 1928.
The Restoration Guide/ Judging Standards are so valuable...all vendors and both MAFCA and MARC sell this book for $30. You might consider buying a copy...lots of information in this manual."

Maybe someone added Roadster doors at some point? Or simply added handles. Either way, it's a '28/9.

 

Date stamped on the lower left of the upper section of firewall.

 

many thanks guys
