Qualcast Suffolk

Gday, I was recently given a Qual cast Suffolf reel mower, I have always wanted an old reel mower & picked up an old beauty out of a mates backyard, It has some superficial rust but eveything is in tact, it just hasn't run for years.

I was wondering if anyone could help me out in identfying the model & year. The carby is a   Zenith 13-TCA-2 which i think i have traced to 1963-64??   The engine no. stamped into the block is 661453 & the mower serial no. which is stamped on a aluminum plate is DR82806K.

I plan to do a full resto jo on it and would like to do my home work before i start.

Any help would be appreciated

Regards, Ben
