Clive,
I think we all understand when things build up inside.It's important to relieve that pressure.I think your message got through to who it was intended and for the rest of us that appreciate your hard work will continue to support you in any way we can.I wish I was good at researching but have always relied on other peoples publications to do my research.That is why I appreciate when topics are researched and documented so people like myself have a reference book to go to for information.
Dennis,
It's too bad you are not up to the task of writing the book.Somebody I hope takes up this task and with all the collectors on the forum that have gas equipment artifacts in their collection can supply pictures and any info they may have on it.I have many pieces in my collection but do not know the whole story behind the Manufacture,training,soldiers being issued and proper wearing and use other than the label on the items themselves.
