Good morning Albert , there are a few rare examples you have there.
1. Yes that is definately a "Chop-bone".... looks to me like the name has come off , and been re-written by someone. The writting looks like it means "Dont know".... but bushy's would use slang "Duno". Think I know who wrote that , he called me years ago and asked about some of the lure model names. From a discription on the phone I probably said " Dont know". Then they have written on the lure themself. Very clever I reckon , but you can see plainly the different ink ages.
2. Deep dan.... and in bloody good condition too mate..
3. Biggoons.... one has an experimantal bib ( the small bib )... for shallow water work.
The other is a "T" bib. On the same principal of the large "Goodoo-Biggoons". Would not be many of those out there. Rupe has a few I think. He might put a photo up of his for comparison to show you.
