Well our Pakistani friend is of course entitled to his opinion, no matter how wrong it might be.
Just do not
ever try and sell your 'valued collection' to ME please, that is all I will beg of you! The mind boggles.
German made stockbooks these days can be very low in cost - I am offering them now for $A15 apiece
for 32 page books - which is where you saw my comments -http://www.stampboards.com/viewtopic.php?f=27&t=35382
And at that price are half
the cost of Hagner sheets. Which is why they are selling so well. Chinese made books are, and have always been for the 30+ years I have been a dealer, a total and unmitigated DISASTER for storing stamps or covers - or anything else..
They were sold here by the millions
literally by supermarket chains in the 1970s and 1980s - mostly KMart and Woolworths.
They cost $2.99 each for a great deal of that time. How do I know - as many I buy still have the little yellow price tag top right cover. "Flying Eagle"
was one the of best sellers of these truly wonderful books.
Sadly in country areas it was the ONLY type of stockbook on offer, so that is why so many were sold.
Near every kid's collection ever formed here from the 1970s is housed in these horrible things.
Now for our Pakistani new member friend - and others - lets have a little eduction lesson here.
Cardboard is wood pulp. Trees are pulped into chips, and the slurry is pressed into cardboard.
Cheap cardboard is left untreated. i.e. it is highly ACIDIC.
Anyone with a modicum of common sense knows that stamp products stored in any Acidic Medium means a death sentence for them.
More expensive board is bleached, to lower the acidity and PH level of the board. Bleaching costs money.
The German makers used that board, the Chinese did not. Simple as that.
Stamps stored in a humid climate like Eastern coastal Australia, or most parts of South East Asia are in a very HUMID environment.
i.e. there is a heap of moisture in the air for months each year.
Moisture and stamps are also a death sentence combination, as it breeds mould or rust or foxing. Moisture absorbed from the air to acidic board, is essentially creating a weak acidic bath.
So lets see - so far we have these wonderful "Flying Eagle"
books 'protecting' your stamps via the weak acid BATH they create Clever stuff. But it does not stop there.
"Flying Eagle" books were too cheap to use glassine strips to hold the stamps in place.
Glassine is a well proven PH neutral paper substance that the Germans have used for decades for that reason. It protects stamps. But it is expensive
. "Flying Eagle" were sold for $2.99, so nothing costly could be used, so they settled for a thin PVC plastic film.
PVC is of course also a disaster to store stamps in, (we NOW realise) but do we think "Flying Eagle" cared?
The thin strips of PVC plastic also had another neat feature that all the $2.99 buyers seemed to like.
It contracted i.e. SHRUNK when it got damp. As of course occurs in humid climates.
So those 8 or 10 strips across each page shrunk
over time - and got "tighter" but the cardboard did not.
Now you do not have to be a Physics Professor to now that this will warp the pages, and that is what one finds on near all "Flying Eagle" type books.
Warped and buckled pages - so that stamps are so tight on 1 side so you cannot move them, and they fall out on the other side when you turn the pages. Brilliant stuff.
The Europeans use linen hinging for securing all pages to the spine. i.e. when you open out 2 pages they lie perfectly flat. And will so do 1000 times as linen is fabric. It will stand the wear.
"Flying Eagle" type books did not run to such niceties. They simply bound the cardboard pages together at the spine. So the pages do NOT open out flat, and after a 100 or so openings, the paper often tears at the spine making the book useless.
Unlike our Pakistani friend who might have a few of these gems, as a dealer I have bought and handled and turned the pages of TENS OF THOUSANDS of these disasters
over my 30+ years as a full time dealer. There is more rust/toning/foxing to stamps caused by these "Flying Eagle" books than any other storage medium ever marketed, and that is a FACT
Whether anyone in Pakistan or India, or Malaysia or Sri Lanka agrees with that or not, it remains a FACT.
Chinese made stockbooks are, and have always been, a total disaster to store stamps in, and that is advice from a professional.
In the same period I have handled 10,000s of German made books. I personally sell 1000s a year in fact.
These comments below are from someone from another planet from where I live as they are just not true - in fact these words sum up the "Flying Eagle" type books, not
the German 'Lighthouse' ones.
Who knows what he was using, but they were not made by 'Lighthouse' who are renowned for their quality.
In contrast stock books from West Germany have been the bane of my existence. They are commonly found with bent pages, ripped inter leaf sheets, sticky sheets which rip when you try to open them, those little rows are stuck and opening them rips the entire thing to shreds.
Aside from the physical defects most within a month or so lose their tightness and start dropping stamps like its raining.
