Columbia~ Seek Gibbons ID if possible.

A brace of Columbian SCADTA semi official airmails,
with Consular opts.
Apparently Scott lists them, I wonder do SG?

Please may I enquire as to what consulate R refers to?
(I am not going to presume :)

Also, in a similar vein, and a random odd request,
I have a GB great western railways semi official airmail
(the Ford tri motor)
Has anyone washed one?  mine is suffering gum toning
but havn't been game to take it for a swim.
The reg number is red, and it may be fugitive.
Thanks.
