Hey Barry ,
I was thinking about your dilemma when I had my Phillie Spin rods out last night .
The Epoxite Spin Rods came with bronze End Caps
My 7ft Salmon Colored (early) two tip rod has the low profile end cap
My 3m Registered rod has the std flared end cap
My Royal spin rod has a bronze seat but gold winding check and End Cap .
My GMS64 rod has the plastic low profile end cap .
Which then spawned an idea For your rod that’s missing the extension.
I scored these Phillipson Cork Checks from a collection this summer.
I have a few in the light bronze and 1 in the dark bronze
You could glue a rubber plug into the cork check cap and then insert rubber plug with cap into rod .
I mocked it up by taping it to the rod butt
Not bad … ??
Then I also thought you could make an Extension by drilling out the cork check fab up a male ferrule that fits with some cork and a Butt cap
I have a nice dark brown Butt cap that was made by National Plastics from Odenton Md
Not sure if Phillipson used them but lots of other rod makers did
Could be semi Factory correct with a Lil’ Maryland style thrown in for good measure.
Just say the word Barry and I’ll send you down some Phillipson Cork Checks for your Project Big Dog !!
