I would really keep the 305 Allan, lovely looking bike and it takes me back to when I was 18 and rode down to Dorking on my CB160 to the BMS (Bruce Main Smith, famous road tester back in the 60's) shop just to buy his Road Test book. The 305 was included (although it may have been the CB72, I dont think the UK got the 305, Ash will know) and it knocked spots off the British bikes of the time with its sophistication. It really does have a classic look to it and judging by your photo its all there, classic biking bliss
