The sealant on the lip has turned brown with age, I'm talking dark amber. The grommets also show their age as do the swivels. The wire gauge and type is original.
Danny's son said in a email to me that his Dad actually did use lips he did not make toward the end before he sold out to Sea Wolf and this lip looks like the ones used on Lupo's.
The previous owner told me he bought it from Danny at his house. He was from the Jersey shore.
As to whether it was rebuilt or finished by someone else my answer is that the oxidation on the sealant, swivels and grommets indicate great age going back to the original build.
I hope this explanation helps.
