My guess is it is 'Mulder'. That is a typical Dutch name.
I did take a look using Google Maps. On Zuiddijk 95 there is a furniture shop located. On 93 a butcher and the neighbour on the other side has a key service bizz. Take a look yourself:on Google Maps
Zaandam is one of the oldest industrialized areas in the world. Famous are the windmills that were used for all kinds of purposes, for example for wood, paint or mustard. Typical for Zaandam are the green wooden houses. Zaandam has still relatively much industry, often located nearby the river 'De Zaan'. Several foodstuffs, like for example chocolate come from Zaandam. Moreover it is where it all started for Ahold/Albert Heijn, a large grossery chain. Zaandam is located directly north of Amsterdam.
Yesterday I bought a bike of an Amsterdam girl. It came from a small Zaandam bike shop, but not Mulder on the Zuiddijk. Another shop. Bike is branded 'Simon', after the family name of the shop owner. The nice frame is built by -I think- OLMO in Italy, but finished in Holland in a paintscheme that shows some resemblance with RIH typical paint.
Will put up some additional pics elsewhere soon.
