I recently got back into my used Machin collection. I'm missing mostly higher value ones 50p+, security, NVI. I'm have so many duplicate values and colours that I'm beginning to collect at a level where I try to identify phosphor tagging type and paper type if possible. I have several questions:
1a: As I mentioned I collect used Machins, so I bought a bunch of mint ones from Royal Mail online (and they come in these great presentation mount!). They don't do favour cancel for mail order, however, so I have to send them back to the UK for a handstamp. With security Machins, can I just affix the mint stamps with their original wax paper backing to a cover so after the stamp has been postmark the whole piece can be removed and put into my album? What about taping the wax paper to the cover? Hate to do it the "normal" way and having to figure out some dodgy method to get the stamp off paper.
1b: For items sent to Royal Mail for special hand stamp, do I need to have correct postage and address for Canada? Will they not put these in a self-address-stamped-envelope? Wouldn't they ruin the stamped covers by putting them through the mailing system? I only send mine in to make them into used stamps so I don't really care about the quality of the cancel. I can't imagine other collectors would want this?
1c: What other ways are there to collect effectively used security Machins from being overseas? As kiloware seldom has the values you want.
2a: To my dismay I recently realise that it is hard to identify phosphor and type on soaked Machins and probably a majority of my collection is already "ruined" because of this. What is the best way to get them off paper?
2b: Is a crisply phosphorised used Machin more valuable than soaked / phosphor-contaminated Machin? Does it really matter? As used stamps are usually low value anyway and phosphor isn't something readily identifiable like flaws.
2c: What's the best way to view phosphor on a soaked Machin? I have one of these:

But it doesn't really work well for soaked stamps. Do I need better lamps?
3: What are some tips to identify paper types on used? OCP, FCP, ACP, PCP?? Any site with pictures?
4: Often times I come across a Machin with a cancel showing full date, or even just year, is very helpful for me to determine the variety, without looking at the paper or phosphor. Is this a reasonable assumption that a certain variety would never be used before the published issue date (on Adminware/Deegan)?
5: Eventually I want to get into displaying my Machins. Do people display Machins by their paper type, phosphor and perforation type (Kampf vs APS)? These are not something easily identifiable in an exhibit.
I also want to share some pictures from my Machin collection:
Isle of Man
Pre-decimal first issue variety only
FDC of the first three Machins
FDCs of the first Regional Machins
Thanks a lot in advance.
