Australian Speedie electric jug?

I see there is a pic of two of these elsewhere on the site... but for the record, here is the jug, base and top. From Jim's collection again!  (Below is a link to the other query re electric jugs.)

What does the mark on the bottom mean?
The light brown jug has the same mark.

They look the same!

Yep, The marks look the same.

Ev, Can you please post the pictures on the electric jug forum and ask what the mark on the Temuka Speedie jug and the light brown jug mean.

Also if they know who made the light brown jug.

I have registered but haven't been accepted yet, so can't post anything.

I am unable to ask questions anywhere on the site, as I always get the same computerised message fault .... something is wrong.
They usually take ages to respond to anything haselnuss, so we will just have to wait. At least I was able to post a new topic.

I'm not sure if this is what you mean but it looks as if the letters and numbers refer to an Application [possibly for a Patent?] Number 550. The jug is rated at 240 Volts Alternating Current and 165 Watts (Or possibly Ohms a measure of resistance?). The other letters or logo may be the manufacturer.

Thank you Tony that is exactly what I was looking for.

So the mark on the bottom should be manufactures mark. Is it a mark that Temuka used?

Do we have any confirmation that Temuka made these electric jugs yet?

This jug was made in Australia.
