Tru-Bal throwing Knife ?

[leadslinger62]

Picked up a used Tru-Bal Throwing Knife. On the Handle there is a 76 stamped.On one side of the Blade there is a 57 stamped on it. Above the Tru-Bal there is a single Star. Is there any value to this? Was it made in 1976??Kinda looks like someone took a Grinder to the one side of but not enough that it could be filed out thanks and take care..

The number stamped on the handle is probably the model #; Model #76 was the "Throwing Dirk".  Not sure what the "57" stamped on the blade means.  The star or stars around the Tru-Bal stamp are just part of the logo, I don't kow if they had any particular meaning or if they changed over time. 

As with so many other things, value depends on model, condition, age, etc.  My brother sort of collects these; from what he has mentioned, a common model in good condition might go in the $50-75 range.  Best bet for getting a better line on price would be to watch eBay.
