Lithuania Scott C63 Varieties

In going over some of the listings for Lithuania in my 2020 Scott Classic Specialized, I am seeing two different varieties being listed with the same catalogue number:

C63a - Perf 11
C63a - Imperf

My regular 2020 Scott volume 4 only lists the imperf variety.

If anyone has a newer catalogue, would you please tell me if the perf 11 variety has gotten a new number (say, C63b)? I would hope this has been caught and corrected by Scott.

Thanks in advance,
Dale

Just checked, no change in the 2021 specialized.

Obviously not newer; but using my 2015 Scotts and it just lists C63-C70 as perf 14/Imperf. I guess this generates a question on my end; is there a variety of the C63 that is perf 11 in lieu of 14?

We need to explain this better for anyone reading this .Especially for those years from now . This set of airmail stamps are normally perf 14 , but only the 5c. stamp also comes in a perf 11 ,as described and listed in other catalogs .

This is a update/new listing in Scott catalog , who ever entered into Scott's system didn't check the complete listing ,because Scott has already used the imperfs listed as the "a" numbers . Maybe since it is one stamp they need to correct this perf variety as a "b" number .

Got it! Thanks for the explanation.
