Up for sale here is this used vintage Greenlee #730 radio chassis punch, number 500 2408.6. It comes in the original box, which has moderate wear and maybe a missing flap or two.
This is a round 1/2" (12.7mm) punch. It has light wear and might have a little light surface rust. This is nice and sharp and is guaranteed to work great for you.
I have a number of other Greenlee punches listed, just search my listings for "Greenlee" to find them.
US shipping and handling is $8, and international is $36. I will be glad to combine shipping, just use "add to cart" on whatever you want, then go to your cart and click "request total from seller" and I'll send a combined invoice. If you have any questions, please ask.
