I am remounting my Russia in a British made album that uses Gibbons numbers. Have most figured out but the 1920's definitives are giving me fits. What are the corresponding numbers for Scott 273-5A- the 1924-5 imperforate issue?
Anyone know of a cross reference giving the equivalent Gibbons #s on early Soviet issues?
Probably not much of a help but my old SG simplified 1992/3 does not list them separately, merely notes that some are issued perf and imperf.
the 3k red/brown SG 360
4K Deep rose SG 361
10K Dark Blue SG 341
50k Brown SG 343
They are listed by Gibbons as 1923.
