Stumped With Hungary 1874-1900 Issues

I have run into a brick wall trying to sort out the Hungarian 1874-1900 issues as well as the 1900 Turul issues as far as watermark and perforation varieties are concerned.
Although Gibbons does simplify the perforation varieties by grouping them together, I am totally stumped by the watermarks.
As the watermark covers four or six stamps, it is often difficult to determine a specific issue unless the stamp being examined has a part of the watermark that can be clearly identified and attributed to a specific issue.
Any tips/help to tackle this would be greatly appreciated.

Check out my Hungary 1871-1916 post for bigblue1840-1940.blogspot.com.

All of the watermarks are shown, as well as the difference between issues. Oriented for the WW collector, not the specialist.

Hope it helps!

Thanks for the link,guess I'll be busy stamping around Hungary tonight
