*PREOWNED* Velmex A2500 Unislide Assembly + Other machinist slide tool 2 Tools

Description

My grandfather was a machinist and also built models. These two tools were found in his machinist tool room where he built the models.
I have absolutely no idea what these things do but they seem to function very smoothly. Everything seems nice and solid and not wobbly or cheap or worn out.
I think my grandfather added a few pieces to the longer tool but I’m not 100% sure because I am not familiar at all with this type of tool. The aluminum he added is bolt on and could easily be removed but this is the way it is going to come to you. Exactly as pictured.
Please take a look at what these sold for on eBay and how low my starting price is. I am currently clearing out my grandfathers estate.
Please be familiar with these two tools. I think they are two separate tools from the same company that do two different things but I am unsure.
So to recap…
Guy Who knows nothing about this set of tools selling in… Exactly as pictured, as described, as found, usable, used condition. I don’t know what they do but they seem to function very smoothly and nice . They certainly do not feel sloppy yet they definitely are carefully used. Thanks, John
