I have a custom blade from Butterfly (it's a kong linghui special with the ST handle of the M.Maze blade), the "special made" from butterfly are comming with a certificate and without any markings on the blade except the serial number. Doesn't look like a custom viscaria at all to me. I've seen several custom viscarias, they come without markings.
The main thing about a special made blade from butterfly is that appart from selected wood and weight, you can ask for special handle, shape...etc...this is written on the certificate.
And Only $200 for a custom viscaria is not the normal price. I've asked for viscaria special made with ST handle it was €250 if I remember correctly (and the blade comes without markings on it, only serial number, a certificate and the silver tag). As for the kong Linghui Special, since it was discontinued blade....the price was even higher.
Seems to be a regular mass market viscaria to me : markings, plastic lens, regular viscaria FL handle....etc....this is a regular mass market viscaria, I fear that the OP had paid $200 for a regular mass market viscaria (and about the weight, its not rare to find new viscarias at 80gr, I've even seen less).
You can see 3 pictures of my custom made Kong Linghui Special in my MX-P review here :

Once again : Only Silver tag and serial number, no other markings and a certificate with deltails of your custom made blade on it.
edit : I took a picture again of the certificate and copy/paste my previous pictures of my KLS :
