A Plastic Keris? for comment.

Hi Wayne , I've been poring over my Tammens and I can't seem to find a real match to any of the dapor he shows in his outline drawings . This , of course doesn't mean all that much coming from me .

It could possibly be a simple Solo blade .

Since the dress is Sumatran , possibly the blade is too ( but only possibly) .
I'll continue poring through the pictures now ...........

The thing that's throwing me a curve is exactly that , the downward curve of the pecetan .

One of the easiest ways to test an object is to find a smooth spot and rub it briskly with your finger several times and then either sniff it or touch the tip of your tongue to the area.Styrene plastic not only gives off an odor(compare it by doing the same to a plastic model car)but will give a burning sensation to your tongue.
Celluloid(an early type of plastic made with cellulose nitrate,camphor,and alcohol)will give off a vaguely medicine type smell.Bakelite(another early plastic)gives off a very strong smell.Resins are probably similar to styrene(not too familiar with them).
If it is found to be made from celluloid,it should be isolated from other knives as when celluloid breaks down it gives off an extremely corrosive gas that will rust carbon steel very quickly.
I've had this problem with vintage pocket knives and it seems to occur at random.I've had several knives that had the scale on one side crumble and fall apart while the other side remained as new.No one seems to know exactly what triggers the reaction,but when it does the process is irreversible.
Just my two cents' worth.
Cheers

To dis-spell if it is plastic or not, here is a close up of the bottom of the face on the hulu. You can see the seam from the end of the beak to the neck, and the many bubbles... sanded seams are everywhere on the hulu and sheath as are the hollow bubbles (you can see them on the sheath edge here but blurry), but of course it is all painted, or chromed over and the plastic is not directly exposed for testing. I hope the picture helps.

Also,

Removing the keris, and looking inside the sheath... it is ruff plastic that has been ground in areas to fit the keris and then plainly painted brown. Where the paint has worn off, it is cream yellow in color.

At a distance, it looks impressive... but up close, it does not stand under scrutiny.

More bubbles (they are the lighter color spots in this picture on the sheath edges and some dark ones too).....

The back detail is terrible (obviously a casting)! Compare it to the first picture at the top of the page.

As for the plastic sheath and hilt. It's hard to tell from these photos.
At first glance, looks pretty real. Only under close scrutiny can you spot it and if the picture is sharp enough.

I guess in future bidders should request the seller for the materials used for the
sheath and hilts.?

What will they think of next? "Maintenance free blades" = Plastic blades.
