general purpose screw plate id help

[acl76]

Can anyone help me identify this set of tools?

There is an image of the label. It says Butterfield and 'General Purpose Screw Plate'. It also lists the sizes of each piece but some of it is illegible.

It contains 42 pieces which is in the other image.

Thanks for any information.

That is a general purpose tap and die set.

UNC and UNF are American thread standards - Unified National Coarse and Fine (the US equivalent of BSW and BSF in the UK) - the main differences are the thread angles (60^o in the US and 55^o in the UK)..

Thanks for the replies.

I tried looking up the company 'Butterfield' but only came across Union-Butterfield. Any relation?

Would these still be useful to someone if I tried to sell them? I'm afraid I don't have much use for them myself.

They are still useful an would work.

Personally if I was to see it at a garage sale I would just keep walking. It's not of high quality or special. Surely someone might pay twenty bucks but it's not me.

Good luck

I cannot tell from the pictures, but the older US made Butterfield tools were pretty good quality.

I dunno.  Middle aged Butterfield was pretty darn good stuff.
And this set looks complete and hardly used.
Worth $100 if you need it and a steal at $20.

I have found no older tap compares to the quality of a new brand name tap. Lots of taps may have been good in the day they were made but nowadays taps are held to a different standard. I don't know much about metallurgy but maybe someone who does can explain how metals an its properties have changed along with heat treating processes.

These taps would still surely work. I am just looking at the life of the tool.

I hope if you sell them you get the most you can. Maybe I am wrong an 100 isn't unreasnonble.

Yes it was Union Butterfield, makers of cutting tools.  and yes, they made some good sets in their day.
they were; Union Butterfield, 134 Chestnut Hill Ave. Athol, Massachusetts.

Athol was a busy tool town not too far from Greenfield, which many of you have heard of in the
tool trades. also Millers Falls.  and not too far from Springfiels or Worcester.

there were many tool companies in this area.  mostly gone today.

I don't know when Litton bought Butterfield but the zip code means it was after the early 1960's.

I buy those different tap and die sets whenever I come across them, unless the pricemis outrageous or the box is really messed up.

My first day as an apprentice started with intrductions to my foreman, and the first two things he said to me were "Can you fight?" followed by "Have you ever ran a threader?"

After that first few moments I spent most of the rest of the day cutting threads.

Chilly,

Just curious...

What did you apprentice in?

Aren't you currently in systems?

The safety glasses warning sticker makes it about 1970 or newer IMHO.
