How are you doing? The wick looks pretty good in the picture, but if you want a new replacement, it can be done. I think the old one was wool felt, I'm not entirely sure.
I haven't had much problems with the plastic Apollo bobbins, other than breaking them during a winding messup. I tend to buy metal ones though.
A new base is a bit of a project, either buying or making. I'm keeping an eye on this thread.
Best of luck
