Identifying the Kenya, Uganda & Tanganyika 10/
King George VI Stamps

Identifying the KUT 10/ King George VI stamps is a matter of comparing these components:

1. Perforation - there are three options - Perf 13.25 and 13.25 x 13.75 which are comb perfs, and Perf 14 which is a line perf. You will need a perf gauge that is capable of measuring a complete perforation range (it should be a series of lines) rather than just showing dots.Comb perfs are created by perforating row and all the columns at once. Line perfs are done one at a time. The result tends to show at the corners. The comb perf stamps will have smoother corners, and the line perf stamps will have some ragged corners.

2. Color - the variation in the center (head) color and frame colors helps determine some of the printings. Please be aware that there is a range to the colors on individual issues, so don't expect them to match exactly. Also, a computer monitor is not considered an accurate method of reproduction. So you may not see the colors accurately. I generally use a piece of black paper under two spotlights to compare my colors. The black seems to help most colors stand out better.

3. A Willingness to be Wrong. Since these stamps were not time and date stamped, you can only hope to be close to right in sorting these printings - especially with the Perf 13.25 x 13.75 issues. So do the best you can and compare any new finds as you obtain them. Be prepared to sort things again when you find something that seems to fit better than your previous estimate. See my notes below each listing to show how I made some of my guesses.

Please see our StampID page for additional details on using some of the tools described above.

The dispatch dates and color descriptions are per "The Printings of King George VI Colonial Stamps" by W.J.W. Potter in collaboration with Lt. Col. R.C.M. Shelton. This is a must for any George VI Collectors which was published in 1952. This reference is out of print, so you will have to look for it as a used item. Two additional listings from the Commonwealth Catalogue were included to enhance the listings.

The catalog numbers are from the 2008 versions of the Commonwealth (CW) Catalogue, and the Stanley Gibbons (SG) Catalogue. Please be aware that the catalogues only list a few of the dispatches, so you will note that most printings are not listed.

It is described by the Commonwealth Catalogue as Steel Blue in color.
Notice the deeper shade of blue compared to the 1952 printing.

Compared to the 1952 and 1954 plates, the King's forehead and nose

less pronounced on the 1938-1950 issues.

Suggested steps in sorting these stamps. We assume you have a number of copies to compare, or this can be very difficult.
1. Measure the perforations. Separate into the Perf 13.25, 14, and 13.25 x 13.75 issues.
2. Eliminate the two printings of the Perf 13.25 and Perf 14 issues based on paper & gum, and colors.
3. Among the Perf 13.25 x 13.75 issues:
a. Sort the printings based on the old and new head plate.
b. Find the claret head plates and compare them to determine the 1949 and 1950 printings.
c. The remaining issues will include the 1944, 1945, 1947, and 1948 printings. Other than the 1944 printing, the remaining three will look pretty much the same. If you have one that does not match because it is a deeper color, it is likely the 1944 printing.
d. Sort between the 1945, 1947 and 1949 printings based on the degree of whiteness in the paper and gum.
