Can Use Some Help With Thai Bullet Money Attribution

This base silver piece of Thai bullet money, also called pod duang, weighs 14.63 g and measures 12.5 mm x 16 mm. I have figured out that the denomination, based on this weight, is 1 baht, same as 1 tical.

Like most of these coins it has two symbols stamped into it.

Here are two photos of each symbol.








I haven't had much luck finding a match in Zeno, Krause, or Google searches.

I have matched up the first symbol (a variety of lotus flower representation) with the Ayutthaya (aka Ayudhaya) kingdom (AD 1350-1767) but this doesn't narrow it down very well.

This first symbol matches up with a 2-tical piece on ebay

https://www.ebay.com.au/itm/A-D-161...12718400619?

attributed to AD 1612-1628 and describing this symbol as the king's emblem "rajchawat." However, I find no other references to "rajchawat" on the internet so am not sure this a correct attribution.

So perhaps I can just say it's 1612-1628, and I don't need to worry about the second symbol, but am unsure about the dating and still curious what the second symbol means.

I've been unable to match up this second symbol, which appears to be a six-spoked wheel.


The first listing in the first table at
http://coincoin.com/I112.htm
describes a 1 Baht bullet coin with a Lotus Bunch (LeMay mark #17 or #31) and a wheel (LeMay Mark #10, listed as C#195 and as ST15 #4. This might be it, but I don't have any of these reference books.

I also see a photo of this exact coin at

http://numis-asia.blogspot.com/2010...nations.html

but it is not well attributed there.

I will certainly appreciate any information confirming or narrowing down the attribution of this piece.
