I went to the PGCA Home Page and found that there are surviving records on Parker 240203 to support a PGCA Research Letter. However, a letter may not address such things as replaced or shortened barrels or even a second set of barrels on a Parker made in the era yours was. But, in my opinion, it is worth the $60 for a non-member or $40 for a PGCA Member to find out once and for all.
