Seeking Advice on Old Mounted Collection, GB QEII Era

You probably need to assess what is worth doing and what is not. Mounting stamps in an album is a lot of work. Getting stamps off paper (like envelopes) before mounting is even more work. Most (but not all) modern stamps [say after 1950] are not worth much. If you are doing this because you want to collect stamps as a hobby then all this work may make sense.

If you are doing this with the goal of selling the collection, it may not make $ sense.

If you are worried about getting hinged stamps off whatever they are hinged on, there is an easy solution. Just use a sharp knife under the stamp and slice right through the hinge (i.e, the crease in the hinge). Then remount it or put in on a page like you illustrated. I have harvested thousands of stamps that way.

Hi, The Wilding definitive stamp issues from 1952 to 1967 are quite difficult to define. the 3 different watermarks are notoriously poor to read, plus the graphite and phosphor issues make about seven sets of, on the face of it, the same stamp. I certainly can't  identify them using lighter fluid and have only limited success using a Signoscope. As they are numerous and low value go ahead and soak a few.

Actually, that is a GB Concise Catalogue count. Most collectors will stop there. There are about ten sets. The phosphors come with green, blue and violet fluorescence. The violet one with 9½mm and 8mm bars. One of the 'Crowns' phosphor set comes on creamy and whiter paper.

Virtually everyone has duplicates. What people do with them varies quite a bit. Some like having dups, some don't. I put dups in a stock book with multiples of the same variety on top of each other, like this:
