Need some preliminary ID help.Inherited Barbados Green, Blue and (Brownish) Black [(21 A2)Scott's says never put into service)].
No visible watermarks using "clarity". US Specialty Multi-gauge seems to indicate perfs greater than 16. Pictures of front and back posted.
Any educated guesses on what perf. or Scott number these might be?? I will send for authentication but do not want to fly blind!
Thanks.
