These designs were supplied by Rick Powall, who worked at Carlton in the 1950’s.

He gave some additional notes:

“Lug pick out was at first done on the top edge of the lug but later this changed to the edge between lug and tube.

Many models had frame tube lining, especially during the 30’s, 40’s and into the 50’s. The most common type was the single spearpoint type, others were the double box, the triple spearpoint and the double box with a Carlton transfer as used on the down tube.

Top stay eye lining was very varied, some examples are shown but many more different designs were used.”
