Many Siamese Mausers are missing the Floor Plate. Here is a way to remedy the situation.
Conversion for Siamese Mauser floor plate from Japanese Model 38 floor plate
Japanese M-38 is on the Left side.
Showing Cuts made to to adapt rear of follower, about 1/16 deep.
On either side of the half Moon area. Leave the area n the
center of the Half Moon for the trigger release.
Cut away material to leave a tab on the rear to lock to trigger
guard, Go slow at the end so as to not remove too much material.
Cut under front of locking plate, on front making a deeper to recess in trigger guard.
Takes about an hour, to cut properly. Check fittin as
you go. A follower form the same Japanese M-38 rifle
can also be fitted for the Siamese.
We did one of these, and it worked great. No we are not making more of these.
Good Luck, Dave
