Wilding Graphite Lines

I have a 1d Ultramarine Wilding , Multiple Crowns Wmk. with a Graphite line variety that I can not find any information on, either online or in the S.G. Queen Elizabeth II Pre-Decimal Issues specialty catalog.
It has a single line down the middle of the back of the stamp, not to the side. Anyone know what I have (S.G. number, etc.)?

We might be able to help if you can provide a picture?

If it does not have phosphor bands, Its probably 1958-61 SG588. Misplaced graphic lines are common on this issue.

Peter--A picture would add nothing to the description.

Dynamode--S.G. 588a Miss-placed Graphite lines are only listed as 2 lines close together on left side (from back) which I have and as 3 Lines. I can find no listing for a single line in the middle. Also, the miss-placed lines for this issue (as far as I know) are NOT miss-Printed lines. They occurred when the Government was using up left over paper to print formats that never used the Graphite Lines originally. I know of no normal issues that could have been the source for the paper for the Miss-Placed lines printings.

The following reference states that one line is not significant and SG 588a is correct.

Antman. Do not take the SG Qe2 specialised catalogues as gospel, especially the older versions. They are rubbish.

cjpalermo1964--That link looks a lot like mine. The one I have is more centered, but otherwise the same. Thanks for the link, But, I still don't know what paper stock could have produced this single centered miss=placed line.

The 2d stamps were issued with a single graphite line. So it is possible that some of the 1d stamps could have been printed on this when they were using up the remaining paper stock.

Clive--True. I was only thinking that the single line on the 2d was always on the side, but since alignment of the graphite line for the use-up-the-paper printings was not a concern, this is most likely the paper source for my stamp.

Crash course in wildings.

Dynamode--Great article!! Thanks for the link.

Thank you very much. Excellent piece.

Glad to help. The article simplifies them enough to be able to basically sort them. The wildings are a great series to collect, especially the high value castles. They are fairly easy to sort. But there are a lot of them, and lots of varieties to collect if you want to get deep into them.

I'd have probably 400-700 of the wildings, taking a few at a time to Wmk ID.
A work in process.

The problem Aussies face are high value Castles, heaps of them, from relatives at home in Blighty, but cancelled on parcels in the main, the resultant stamps are basically ruined, that goes for the later castles and high valued Machins.

Couple of tips for roughly sorting wildings.

If you have a uv lamp, check for phosphor bands. If they have phosphor bands they are multi crown watermark.

Looking from the back. If you think you see a watermark, they are probably 1st or 2nd watermark. These are more visible, and can normally be seen by holding up to light. The multi crown watermark can be difficult to see sometimes, even in watermark fluid. If you cannot detect a watermark, then its multi crown.

You can find watermarks inverted, sideways, and sideways inverted. All are listed.

Again, thank you.
