I now have all but 2 of the 1974 $2 prefixes. Still looking for BP Modified Tint and *RD.Enjoy!
Congratulations, a great banknote, you do have a Museum piece!!Enjoy the banknote!!
The *RD will be a challenge as there are currently only 3 examples known if i remember correctly. Im surprised you never found a BP modified tint, they are fairly common. Its the original tint that is the hard one to find.
