Thanks folks!
I'm working on a new Palo hingeless album, which doesn't give catalog numbers, but lists color. There is no brownish-rose shown there or in the Scott catalog. Here is a new scan for side-by-side comparison of the examples of this design that I have.

Does Stanley Gibbons list an issue date for SG#22? Scott only lists #6(dull rose), #13(rose), #13a(rose lake), #13b(bright rose), #18(rose), #18a(deep rose), #18b(dull rose), and #21(rose) with issue dates of 1862, 1863-65, 1863-81 and 1882-98 for each major number variety. Just trying to figure out where I need to insert the extra mount on my pages!
Thanks again,
Al
