When Indonesia was still under Dutch rule, Jakarta was known as Batavia and Jalan Hayam Wuruk was known as Oost Molenvliet Street, an interesting street with a river in the middle. At number 51 was the Royal Enfield dealer, Lim Tjoei Keng. Here is a picture of the dealership from "REVS",
Here is another view of the street, with the dealership on the left, found serendipitously (someone was auctioning a postcard with that image on ebay!), According to Google maps, this is what that address looks today. Is that brown roof still the same building? Could someone send me a picture of it today so I can update this post?
Update: So I was contacted by a family member of the owner of the dealership! He does live in Indonesia anymore, but he pointed out that the place is now a Toyota dealership and it does not appear much, if any, of the original building still exists. He also sent some pictures of ads,
