Note: R1/4 were originally discovered in a private document archive belonging to a family in Oman, though a handful of other examples have surfaced in recent years. A fifth value in black (illustrated at right) has also been recorded, though the image is insufficiently clear to confirm the value, which might be 3 rupees or 30 baiza (=2½ annas).

Notes:
1. The 2 anna (which is inscribed one-eighth rupee) and 5 rupee values are currently known only as imperforate proofs in complete sheets (of 20 and 16 respectively), and it is not known whether they were ever issued.

Note: the stamps illustrated above are a previously unrecorded type printed by Waterlow & Sons in sheets of 100 (10 rows of 10). The design includes the Omani coat of arms at bottom left, and is inscribed at foot with the name Dhofar, a region of Oman which at certain periods of history was governed as a separate political entity. The stamps shown are denominated ½r, 1r, 2r, 3r and 5r, the currency being in rials. I do not know whether these stamps were ever issued, and would be glad to hear from any reader who can supply any further information about these stamps. I am grateful to John Copeland for sending me the above images.

Notes:
1. The dates of issue are known from the sets of proofs which are housed in the British Library. The first issue consisted of the set to the 1r. This was approved in May 1972, and would have been issued later that year. A new printing of four additional values (1½r, 3r, 10r and 50r) was approved in October 1974, and probably came out by the end of 1974. The date of issue of the 5r is not known. The proofs also show Harrisons as the printers and a sheet size of 50, though the format is not known.
2. The British Library material shows that the original (1972) issue also included the 5b magenta, 10b pale mauve, 25b greenish yellow in small format and the 200b apple-green in larger format. I have not seen issued examples of these stamps but it is very likely they exist. Numbers have been set aside in this listing for their future addition.
3. Barefoot lists a 4r yellow. I have not seen this value from this series though it may be an erroneous listing for my R58 below.
4. Recorded printings (this list is assumed to be incomplete):
R34. 50b grey-blue
R35. 100b pale greyish lilac
R37. 250b deep yellow
R38. 500b dull pink
R39. 1r blue-grey
R40. 1½r red
R41. 3r deep green
R42. 5r violet
R43. 10r brown
R44. 50r deep blue

1989 (according to Barefoot). Similar to previous issue but redrawn with Revenue in slightly taller letters, and without the floral background. All values 22½ x 28 mm (no smaller format for low values). Perf 14¼. No wmk. Printed by BDT International (imprint in lower margin). Arms and inscriptions in black; background colours given below.

1998 (earliest recorded usage). Design again redrawn, with the English inscriptions at top in taller thinner letters as illustrated at right. Perf 13. No wmk. Arms and inscriptions in black; background colours given below.
Two different sizes:
a) Smaller format (21½ x 28 mm)
R71. 100b pale greyish lilac
R72. 200b salmon
R73. 250b yellow
R74. 1r blue-grey
R75. 1½r scarlet
R76. 3r olive
R77. 5r violet
R78. 10r brown
R71. 100b pale greyish lilac
R72. 200b salmon
R73. 250b yellow
R74. 1r blue-grey
R75. 1½r scarlet
R76. 3r olive
R77. 5r violet
R78. 10r brown

b) Larger format (22½ x 29 mm)
R83. 250b yellow
R84. 500b claret
R86. 3r olive
R87. 5r violet
R88. 10r brown
Notes:
1. The unit of currency on R71/72 and R83/84 is now correctly shown in English as baisa, not baiza as on the previous two issues.
2. Earliest recorded usage (smaller format): 1998 (100b), 2000 (200b, 5r). The document illustrated below shows a receipt for 200b fees paid in three stages on 22nd February, 8th March and 22nd March 1998. The first two payments use stamps of the previous series (my R51/2), while the third shows the earliest usage of R71. From this I infer that R71 - and possibly other values of this set - were issued in mid-March 1998.
3. Earliest recorded usage (larger format): September 2011 (5r).
4. Illustrated here is a crudely printed forgery of R84. This was evidently intended to defraud the authorities and was successfully used to pay duty on an examination certificate.
