Hello Big Norm,
At page 90 of my book you can see the Siamese LP08 number 3511v with his unmatched stock number 3475. The picture shows the left frame and you can easily see the serial numbers and the Crown/Crown U on the receiver. The stock doesn't show the Mauser Banner although some Siamese models are reported with this.
I hope this helps.
Ciao
Mauro
