English Pottery Hallmarks Advice Please

[needawin]

I have 2 items with hallmarks but am unable to pinpoint them on the hallmark web sites.
Can anyone advise please.
One is a floral jug with the mark etched on the base
E.27
Rd No 818666

The other is a vase with a print on it. Bit obscure but looks like a globe of the world with longtitude and latitude lines on it.
Flag or pennant above. A sash round the globe. Unable to make out first word on sash but second word is "WOOD".
The number 3604
I. Is below

I personally can't tell you but there are the following groups on Facebook: 1. Study Pottery Appreciation & Identification
2. British Studio Pottery Mystery Pots
3. The Ceramic Collector

One of these might be able to help you. Good Luck.

For the floral jug, the RD No seems to indicate year of registry as 1937 - scroll to "Mark C" here - https://tinyurl.com/y59ntn6p

Have you tried this site? There's a reference to Rd., don't know if it'll help.
