Have fallen heir to what looks like a Premier Crown Kit. (Early 80''s I think? so not vintage) Does anyone have information as to it's shell construction and any other useful info?

Info re this kit seems to be a bit limited on the various Vintage ID kit sites, any help would be appreciated. Finish is PR (poly) Red so seems to tie in with this date range. 95% sure its a crown kit, but doesn't have the crown logo beneath the Premier badge. pretty sure it's not a Resonator or Elite Kit,

(nor Olympic / Beverly / Club range as it's pretty loud!)

Keep on Pl
