Rouletted Vs Hyphen Hole Perf

I have a few battleship revenue stamps and have been trying to determine if they are rouletted or hyphen hole perfed. How can I tell the difference. I have attempted to attach a couple of scans. This is my first time to try to put a scan up so hopefully I did it right. Thanks for your help.

You did a bang up job eopie, with the scans.
Generally rouletted do not receive a "punched" hole,
I'll post some examples for you.

Hyphen hole

Excellent illustrated resource, Rod!

In hyphen hole perforations, paper actually removed from the stamp; in rouletted stamps, there is no paper loss.

$1 at auction,....what a hobby!

Crikey!
Samuel's stamp den is nearly as big as yours, khj

There is one noticeable difference.

He has walkspace, I have crawlspace.

So with the two examples I put up both of these would be rouletted correct? I have a stamp I bought on auction that was suppose to be Hyphen but it looked like the rest and wanted to make sure that I was not missing something. Thanks for your help.

I am guessing eopie,
the first is hyphen hole the second rouletted,
for a novice like me, I need to see them joined first
to see the "hole"

I am using the size of the "tooth" left when they
are torn apart as a guess.

Top one is rouletted, bottom one is hyphen hole perforated.

That top stamp upon cursory glance, does appear to be hyphen hole perforated, but see red and green circles in the picture below.

Yes, looking at the top edge of the top stamp, it "appears" to be like hyphen hole. But if you examine the bottom edge of that stamp, you will understand what has happened. Compare the red circles. The bits of paper you see sticking out at the top edge are not because hyphens have been punched out in between, but because part of the stamp that was originally above it have been torn out. Compare the green circles and you will see the same thing in the left/right sides.

I agree, sometimes it can be very difficult to tell, especially if the perforation is weak, as in the bottom stamp. However, another way to tell is the gauge -- roulette 5.5 while the hyphen hole is perf 7.

By the way, for this stamp, the quick way to distinguish is by simply counting the number of slits/holes there are on either the left or right side within the vertical length of the stamp design.

Fine examples of Sawtooth Serrated Roulette's from Spain......
Indicating their susceptibility to tearing
so scissors employed.

Ha-ha! I thought I recognized those passages rod! I have the same book! Great thread, very helpful.

Here is a look at the 2 different Perforations.

Rouletted



Hyphen-hole

Yep, Grossman produced a great reference there ILS.

Stallzer! great pair of blocks, these are becoming
one of my favourite top 10 stamps, for me
that is almost a perfect design, lovely stuff.
