Hi Glenn noticed a few volcano stamps from the Philippines that you have not featured and thought you might like. Hope these are useful. They feature on my topical web site which includes Philippine volcanoes where there are some more details of the volcanoes but also some subsidary stamps such as mythical creatures said to reside on a particular volcano and volcanic geology. Introduction page for Volcanoes on Philippine Stamps (topicalphilippines.com),
Best Regards Mike
Laguna Volcanic Field Scott 3606b (2015)
Scott #1090 (1972) Mt Apo in the background
Scott 2508 (1997) again Mt Apo in the background
Scott 3302a (2010) Mt Makiling
The next all contain Mt Mayon in the detail and one is a 'volcano on stamp on stamp'
And finally some unidentified
I suspect this is Mt Baco on Mindoro island.

It is the last stronghold of the Tamaraw.

The geology of the Mt Baco region is complex including metamorphics, sedimentary formations and some volcanics. From my quick research its not clear if Mt Baco is a remnant volcano or simply a generic peak within a metamorphic/sedimentary mountain range.

I've had a look at your 'Unidentified or Possible Volcanoes' section.
I offer a few possibilities:
I'm pretty sure this is Mariveles (https://en.wikipedia.org/wiki/Mount_Mariveles).
Our lady of Guidance church is on the eastern shores of Manila Bay https://en.wikipedia.org/wiki/Our_Lady_of_Guidance
Mariveles and adjacent cones lie opposite the city of Manila across Manila Bay. The profile is a close match to that on the stamp. What do you think?
Hello Mike, lovely to hear from another volcano stamp enthusiast. Your website is fabulous, I love the stories you've included with each stamp, particularly the fairy stories. I have been to many Indonesian volcanoes and they all have fairy stories associated with them, including a few stamps. I have added yours to my database, thankyou.
I've attached my Excel list of Philippino volcano stamps, it'd be great if you can cast your eyes over it for inaccurate or missing stamps.
