Mexican Stamp Questions Please ?

Hello all,
I've been working through 40 hinged pages of pretty nice Mexican stamps that have IDs in what I think is Michel cat. #s & are re tagging them slowly to Scotts.
Most are easy that have "no wmk." listed & marked, but now I'm starting on the ones with watermarks & it's a lot harder to work out with them on sheets.
I don't want to remove them or damage any trying to see their backs.
Can anyone help by telling me what the cat.wmk.# for scotts would equal for these cat. #s please....wmk. 67, 125, 167, 191, 206.
(206wmk. seems to = sc.279 wmk.)
I'm coming across things that are not marked as well & would like to list things like the centre shift & this affect on this stamp under them, but not sure what to call what's showing in the lower right corner of this one ?
Thanks for looking.
All the best....Jad.

Looks just like chill roller doubling, but I am not sure if the press this was printed on had a chill roller.
The small letters on the bottom seem to be doubled also.

I don't know what those wmk are " wmk. 67, 125, 167, 191, 206 " They are not Michel, Mitchel don't use high number like that.

What is a "chill roller" ?
Not heard of this phrase in 25 years of collecting.

When you mean that you have Michel catalog numbers and want to know the corresponding watermark numbers in Scott, here we go:

Michel C# -> Scott wmk#
67 -> listed in Michel as no wmk
125 -> listed in Michel as no wmk
167 -> 152
191 -> 153
206 -> 154

SWH, where you get those # ? In my 2008 Michel they use number 1 uo to 14 for Mexico wks

EDIT ok I get it; you means the stamp Mi206 ( with Michel wmk 5 ) as a Scott 154 wmk

Check!

Thanks for all your interest.
Sorry I was only guessing they were Mi. as I couldn't find any on the web that showed they were Gibbons. I don't know about any other cat.s for Mexico....yet ;)
Maybe this might help as one of you is bound to know what is meant on the sheets & which cat. they are from.
Thanks for your help & input all........Jad.

Jad, the following numbers are definitely Stanley Gibbons: 860, 861, 940, 941, 942, 944, 949, 950. So one would assume the others are too. The other stamps are from a long running 'Mexican Culture'set - 1950-1976 - that came with many varieties. I cannot check these because I only have the simplified 'Stamps of the World' catalog that does not list varieties. Maybe someone with a proper SG catalog can dvise you further.

Outstanding SWH, many thanks for your time mate.

I thought I maybe able to norrow it down by check stamps that only come with one wmk. or none & was able to work out that wm67 must be sc156 wmk. by the likes of these.......




& I think maybe confirmed the wm206 as well with this stamp, it looks like they may run in the same order as Scotts do in the std.cat. I have.




I've got to share what I just found with you all though, I have 12 of these but one nearly jumped out of the sheet when I tried a LED torch from behind the sheet. The lower one of these two looks to be on vertically laid paper, so far I can't find any listing for it, or anything on the web. A good night :)
ATB.....Jad.

Rod222, I was not ignoring you when you asked your question. Probably dreaming of stamps by that time!
I collect Transportation Coils, and the only time I have ever encountered then term "chill roller" is when talking about the now obsolete Cottrell presses. I will quote from the "PNC3 catalog of Plate Number Coils - Illustrated Glossary":
"Near the end of each printing unit is a Dryer, the main purpose of which is to dry the wet ink on the substrate (paper) prior to the next printing unit. A Chill Roller is mounted at the exit point of each dryer to insure the web enters the next print station at ambient temperature."
Sometimes, when too much ink was applied the chill roller picked up some of this ( still wet ) paint and applied it back to the web. Almost doubling part of the stamp. Hope this helps? "Chill roller doubling" is fairly uncommon on most Cottrell printed issues, but some of the best ones are to be found on the 20 cent Fire Pumper ( Scott 1908 ) printed from plates 5 and 13.

Thankyou Peter,
saved in my database.

Nice airmails Jad!
That 20 cent is a real nice EFO

Thanks Peter from me too for the details, I have to admit I didn't understand the term. I've tried to rescan that area better for you, but it doesn't come out as well on a sheet. Best I seem to be able to get.




.................

Ciletaliph...glad you like them, I've got some more for the Airmail thread saved & will get them on as soon as I can

.................

The torch hasn't helped with the wmks. but it has found 5 little expert stamp marks on the backs of the stamps, 4 are a red capital B inside a red circule & the other one I can't make out yet,.... another interesting night.
All the best....Jad

This stamp was printed on a Waite-Saville die-stamping press - sort of hammer device! But with the hammer making it twice would have not just that area doubled! ;)

I'd rather suspect it to be a so-called "plate flaw" ...

jad: visit this web site for more information about Mexico stamps ( http://mepsi.org ). It's the site for the Mexico Elmhurst Philatelic Society International. There is also a catalog just for classic Mexico through about 1910 or so: the Follansbee catalog. You can find out much of what you need to know on the site. If you plan to continue with Mexico, I advise becoming a member of MEPSI. I joined in 2012 and have been very pleased with the publications. Nick Follansbee also does a Mexico-only public auction; usually in Reno, Nevada, USA; about every year or so.
