Hi there folks,
I would like to ask for some help identifying the following stamps correctly? I would appreciate any and all feedback or comments, and Thank-you for your time!
I believe all these overprints to be TypeB- letter 'A' with sharp pointed tops, but looking at the scans I am not sure?
Stamp #1-3:
Canal Zone 1925-26
#73 (A157) 2c. Carmine
or
#84 (A157) 2c. Carmine



Stamps #4:
Canal Zone 1925-26
#78 (A169) 15c. Gray
or
#90 (A169) 15c. Gray

I appreciate the help, Thanks again!

Have a Good One,
