Postage Due Markings Query

Hello All,

Attached scan shows two postage due markings and I would like confirmation that the letters I. S. stand for Inland Section
and the letter D and H are the initials of the relevant hand-stamp used.

I have found it very difficult to garner information on these marks, despite web searches and checking our reasonably good selection of catalogues. Though they are illustrated in three catalogues that we have, none of them explain what the initials stand for.

Does anyone know of a good site dealing with postage due markings?

Regards.
Ron.

I believe that the I.S. stood for Internal Section. The other notation you may come across with the postage dues is F. B., which was Foreign Branch.

Do you have a source for 'Internal Section' or is that your understanding of it?

Rod,

Thanks for that information though it was I.S. rather than I.B. I was interested in.

Update on this from Great Britain Philatelic Society

"Ron, great source is the Postage Due Mail Study Group. There was a series of 6 articles on these stamps 2002-2004 in great detail especially about the letters. Anyway IS is for Inland Section and FB Foreign Branch. The extra index letter is presumed to differentiate various handstamps of the same denomination. That way a check could be made on who or which group had actually taxed any given item.
Regards"

So it seems my supposition was correct.
Regards to all
Ron.

Apologies

That's cool Ron....
we all miss stuff.

Sorry the info I posted was wrong. It was from an old posting on another site, and not corrected at the time.

G'day,

22crows.... No worries, it is pretty hard to keep up with things all the time.

Thanks for the scan, appreciated.

Penguins,

I regularly refer to:

'British Postage Due Mail 1914-1971" by Michael Furfie, he is an active member and contributor to the Postage Due Mail Study Group mentioned above. It is only £6 for membership to the group and a great resource.

I also refer to "Postage Due in Great Britain - Stamps and Postmarks" by Curt Fernau and "Unpaid and Underpaid Mail 1840 to 1921. England and Wales" by R I Johnson.

I also have 'The Book of T" by Edward Leahy in soft copy. Can email to you in you PM your email address.

Hello John,

Many thanks indeed for that information.

My original query was on behalf of someone else so I will pass your response on to him.

Many thanks for the offer of the Book of T but I think he would not go too deeply into it. Very much appreciated though.
I did pass on the information and url of the Postage Due Mail Study Group as well.

Regards.
Ron.
