I don't have any paperwork for my 77K Venom Lazaglide but I contacted HC with the serial number & they replied that it was sold to Venom as an action only on a certain date in 1985.
It also has the Venom & Lazaglide stickers (no cobras) which are both worn & barely visible. The stock however, is standard but the internals are definitely glided.
Had a brief thought that a new sticker would be nice but then if I ever did sell it buyers might think the gun was a fake!
