Paul I have literally a thousand blanks now unknown names disappear from both the memory and physically from the timber as marked over the passage of time. One could label blanks by several names that could look correctly labelled because within each species there are so many variations.
Having explored your pen for possible names the conclusion is its a beaut example of timber at its best a lovely pen as well. I read all the fanciful names given to acrylic blanks completely unrepeatable in manufacture and say what the heck have fun and enjoy. There are set answers people will give what wood? etc you could research for even days and still be wrong. A great scientist a famous author in Australian Eucalypts armed with Fruit. nuts, leaves samples with the grain against the grain of the timber I know as Brown Mallee he came up with there is no such thing mate its a member of the fine leaf Mallee family but still as a sincere fan of supposed Brown Mallee very few people will ever know the truth but specify Brown Mallee when they want some.
What I am saying is a Rose by any other name is still a beautiful thing IMHO. Some timbers are dead easy to identify also the loose term Eucalypt Burl covers best part of a thousand Eucalypts we all nod our heads sagely and accept this as well. Another huge anomally is Goldfields Burl another broad brush naming about as useful as a sore Tail to a boundary rider but spruiked all over the world indeed a broad brush classification. In Australia there are umpteen common names for every tree that grows in the bush country, the most so called Oaks are only related to Quercus by association any way.In my wood group we have foresters and scientists who develop a set frown scrape a slice pontificate with basic remarks and great satisfaction this is a hardwood, a softwood etc and two weeks later spend the intervening time studying text books etc finally pontificating its this or that.
I have a mate called Barry Moon who delights in saying to me go on show me various pieces of timber for me to identify cause he has never been proved wrong he is a true bush bloke earned his way through life felling , milling, building all over Australia using a strong portable mill etc he is one of the few really expert identifiers I have ever met. For recreation occassionally he will leave about 2 hrs journey from where I live to go to the Gulf Country at the top of Australia just to go fishing(have a look at a map of Australia its many thousands of kms). Recently with another mate they went to Cunnanurru real thousands again and harvested my main favourite Conkerberry, can you imagine the effort and again real costs of cutting milling and carting back to my way. He was asking twenty dollars a kilo and you could here the moans from here to Queensland about how much etc.
Thanks for listening Paul would have been real easy to say havnt a clue mate, love then pen allround mate.
Kind regards Peter.
