Welcome to the club, you have come to the right place for Monro information.
I am the club custodian of the factory records, your machine was despatched on 23-2-60 and delivered on 24-3-60, unfortunately the customers name and address are not recorded for this one. The source (dealer) is shown as Walter Wood, invoice number is 35463 and it would appear they were in W Sussex as other machines from the same source have gone to customers in that area.
The original colour is an odd metallic, sort of hammer finish, blue/green/grey mix.
If you need an owners manual let me know (see my advert in the club magazine, The Cultivator).

I see you bought from me via that well known auction site, posted today.
A lot of us have more projects than time.

Quite a list.
