I'm trying to find out more information about this old loop frame bike I'm planning to refurbish. I haven't found any other marks that may be identifying, if there's anything else I can take a photo of that might help, please let me know. Other information is that it was bought locally in Western Australia, so it's likely that it was bought either here or somewhere in Australia.
I found an identifying name on the rear hub and coaster brake lever, photos added below, I can't quite make out what it says. Also, I had a response from the WA Historic Cycle Club saying that the chain ring looks to be a Williams and it should have a date code that can be decoded here: http://www.classiclightweights.co.uk/williamsdating.html
Started pulling it apart and found a stamp on the chain ring that has a "46" in the middle of text circling it "BAT.NO.10898-47" The letter at the beginning is worn, but I'm assuming it is a B. The drive side crank has the "B.T.M" stamped on it. I haven't been able to find anything useful from those. There may be another stamp, but the paint is quite thick in some parts so it's hard to tell. Images of these are below.
So I've started removing the top two blue layers of paint to reveal the original paint(or what's left of it). Unfortunately, most of the likely spots for logos or names have been sanded previously.
There is a logo of some sort on the seat tube along with another dutch flag at the bottom. You can also see that there is dark green paint in the middle of the seat tube and it looks like there is a dark pink/magenta colour down the bottom. This matches with the down tube that appears to be magenta faded to dark green(possibly grey or a lighter colour in between?)
The drive side down tube has some brighter bits of paint where there was previously paint or stickers. On the non-drive side of the down tube I think I can see an "e".
I'll continue removing paint, it's quite time consuming, I'm using a hobby knife to lift off the old paint. This still isn't much to go off, but it's a lot more than before. I've also included pictures of the handlebars and stem, I tried cleaning them up a bit to see if there are any stamps, but I can't see anything. Please let me know if there is anywhere specific on the bike that I should focus on.
I've made the biggest discovery by far today, I've added the picture in above all the others. On the steerer tube there is a label with what I assume is the manufacturer's name because it's a guarantee sticker. Unfortunately I can't find anything about them except that they maybe part of "The Nissan Cycle Co." You can see the label below, it says "Super Yama". Hopefully someone knows something. You can also clearly see one of the original colours, it was hidden under a crown cover.
Just found another thing on the WA Historic Cycle Club site, they have a page with WA bike manufacturers logos, and I'm almost certain this is the one on the seat tube, I've added the logo down with the pictures of the seat tube.
