I wonder if those long tangs were added to the fork instead of being original. The brazing seems very sloppy considering the lug work looks good.
Do you have a caliper measurement on the seat post itself? The seat tube looks close to 26.8.
Also, the lack of any date codes on the cranks indicate they were made before 1973 and after 1968 (I think) when the 144 bcd versions were introduced.
