There were at least two types of loops used on the frame for the hydraulic drum brake line and yours appears to be the type used for 1958 to about 1969.
Notice the rectangular boss above the swingarm pivot bolt hole. That boss was drilled and tapped for 195864 but yours appears undrilled so that indicates your frame is 65 or later.
I see no sign of a reinforcement gusset on the downtube. Said gusset was introduced as standard fitment for late-68 and later. So the lack of a gusset, combined with the undrilled boss above the swingarm pivot bolt hole indicate the frame is somewhere from 65 to early-68.
The square-tube swingarm is 1973 or later. Eric

Have a look on the left side of the steering head and you may find what are sometimes called additional original component identifying numbers, aka anti-theft numbers. If they are present they may consist of one capital letter followed by either three or four numbers but they are small characters so you'll need to look closely. Letters used for 1965 models were C or D.
The photo below shows B5+++ on a 1963 model frame as an example of where to look. Eric
