pretty sure 1st alloy rims were Rudge,seen a very early Palmer brand jointless alloy rim ,(huge big weld across the join
),they were lipless,Boranni bought manu rights from Rudge (hence the Rudge "hand" symbol as a nod to inventer),your'e pretty safe with mudcatchhers pre 65,Dunlop was doing them in the late 50's,would be splitting hairs using akronts,same style??,
ps disclaimer,didn't use google,went off memory instead
