One of those things I collect and use are old leading tools.
I think they were all made by Heller and sold by others, there seems to be a lot of that in the auto body tool market.

nice.   don't think i've ever seen the "shorties" before.  thanks   

Leading tools as in filing down auto body repairs done with lead?

Yes, file down the high spots, save the lead/tin remelt. small spots, or close to a body bead or detail.
There is a little bondo on some, it's hard to get off, makes a mess on a wire wheel.  Not what they were made for.

Hello, Oldgoaly. Thanks for posting. I have one of the Reveal Tool Holders around here somewhere. Good to to know it was made by Heller, it is unmarked. Your post also confirms that what I have is made of brass. I see a lot of the longer Vixen files when I am out and about, but I have never come across the short version.Regards, Lou
