Dad’s 1964 moulton classic – advice on restoration

Hi Bikewrench, sadly my dad passed away a few years back and he always had in mind to restore this Moulton.

I used to be pretty handy with bike builds back in the 90’s 00’s but haven’t delved in years.

I’m thinking of taking on this project to restore it back to as original as possible and in ridable condition again as a tribute to him.

Any advice / info on these Moulton’s welcome.

Thanks 👍
