Seahorses Question

My guess is: first two and fourth are 1918 (Bradbury)- but unsure about third because of the colour. Any information about identifying these? And the cancellations: first is Leicester, second maybe `ORPINGTON`?

There are 3 versions. 1913-18 (SC173 and 173a) 1919 (SC179) and 1934 (SC222). The 1934 are listed as brown and can be distinguished by the crossed lines in the background of portrait. Previous issues have horizontal lines only. The retouched version of 1919 have a dot above the middle of the top frame. These are 22.75mm high whereas the 173 is 22mm high (the design area, not the dot).
Time to get out the magnifying glass and ruler.
Goodluck.

Also. The 173 were printed by Waterlow Bros. & Layton. 173a were printed by Thomas De La Rue & Co.
The 179 were printed by Bradbury, Wilkinson & Co. The 222 Were printed by Waterlow & Sons.

Orpington is a town in Surrey [Greater London], not far from Croydon and Bromley.

Thanks, the `dot above the middle of the top frame` is knew to me! I have a few Croydon cancellation on Machins, but never heard of Orpington, and the pmk is blurred. Now is clear (it`s hard for me identifying places in Great Britain, especially those having no football-team at all or playing in lower leagues Conference]) Leicester was easy...

Orpington FC play in the Kent Invicta Football League!

Your orpington is a beauty.

Slightly blurred as it is a rubber, parcel cancellation.
I have seen rare ones go for >$60 Alderney etc.
