First off these are not mine. They belong to someone I know. I can get the two of you in touch if your interested.
I have 3 Uniguards (4 if i can find the cast bracket)? from a school sale lot all have damage to the part that covers the blade. all come with the cast bracket. I checked at Ace and the parts are still available. I would think that the current uniguard clear plastic blade guard would fit this also.
$20.00 each plus shipping. Or save me a lot of work and buy the lot for $50.00 Please don't ask me to quote shipping it should be around $20.00 but you can check my zip is 92591
