So, this is what I have for this topic -
From a 1954 Plumb catalog I just got, it shows the Plumb All American label I show above in the one pic - thus showing this label was in use as early as 1954, if not earlier -
This then shows the axe I gave the picture of can very well indeed be pre 1980, as I have claimed it to be, based off of what my dad told me.
Also, in this catalog is has a excerpt from a Plumb meeting in 1974, which is a great read. This is from the Early American Industries Association -
In the Plumb meeting notes, it does state that Permabond was only used on the high end line of Plumb axes until 1974, then all axes went to Permabond technology, including the All American line, which is listed in the catalogs as not showing Permabond technology listed - from this same catalog 1954( you can see where it states Permabond or not)
The excerpt from the meeting -
This then justifies my claim that not ALL Plumb axes were utilizing Permabond technology post 1955. To claim they did just doesn't make sense based off of what I have seen out there, in my collections, others, on ebay, etc. Overall Permabond numbers in axes are very low compared to the total out there.
One question left though is just how old is that All American Axe that I got from my dad - I will have to dig deeper into that.
So there you have it. Hopefully we can put this to bed now.
