Single Line Framed Registered handstamps

Three Single Line Framed Registered handstamps are known (Campbell, p. 78-9):

• Calliope Single Line Framed Registered handstamp (42 x 8 mm) -  rated 5R - $100
• St George Single Line Framed Registered handstamp on a Sideface (43 x 7.5 mm) -  rated 2R
• Yaamba Single Line Framed Registered handstamp (44 x 8 mm) -  rated 3R

These three post offices opened in 1864. Campbell speculates that Allora and Sandgate post offices (both opened in 1863 and which do not have the usual small type two-lined registered handstamp issued before 1873) may also have used these Single Line Framed Registered handstamps, probably on Chalons.

I have seen tied examples for Calliope, St George and Yaamba. If you have any examples on cover, please email me so I can show them
