Tools found in my new (old) machinists chest

[GreatOldOne]

I found these in the tool chest I bought a couple of weeks ago…


Some I believe are apprentice pieces, others purchased by Mr Thurlow during his career, and some he may have ’forgotten’ to return to stores




the center finder and what I believe is a depth gauge are obviously scratch made - as is the 1/8th inch parallel



Then there’s this imperial radius gauge - in increments of 100th of an inch… I’m not sure as the markings are a bit worn and don’t seem to follow a pattern - the largest says 4 1/2, but the next is 45. The first is definitely not 4 1/2”, but the second is probably 450 thou… I dunno. I’m metric.




There was also a set of BSF 7/16 taps


And the reamers you can see in the first pics. I think that apart from one straight one, the others are tapered pin reamers. The second to largest states it’s a no 4. The smallest is a 0. The others are impossible to read. How would I identify these mystery reamers?

Finally there where these:



some sort of starrett adjustable square (no. Unknown), a starrett fishtale, and another fishtail with and adjustable depth gauge thing. I can’t make out the maker, but it was born in Boston Massachusetts.



can anyone identify it?

cheers

Jason.

Wow, those are some nice looking tools. I have to chuckle a little about the radius gauge — “Slip In”, No 220. Is that the UK equivalent of “Snap On” ? The centre finder (the question mark shaped thing?) is especially elegant though, I’ve never seen one designed like that. Very nice stuff.

The Patent date is Sept 11 1883 on that threading gage.
I can't assume that all those tools were found in the condition pictured. That would be a type of miracle.
Please describe what processes you used to clean them up.
All look very good and don't seem damaged by your cleaning method(s).

That is one clever center finder; had not seen that design!

Some of the measurements that seem "disconnected" from the real world may well be in reference to specific parts as defined by a drawing. Then there is the possibility of threads being Whitworth versus Unified Standard. (55* vs 60*) The date, 1959, implies an apprenticeship to very old standards that existed then but haven't been seen in years.

To clean them, I used some methylated spirit - meths to us Brits, denatured alcohol to our American cousins I believe. That got most of the grime off. Then the items that had corrosion got a dunk in some evaporust. Then everything got a light buff on a worn wire wheel. Finally everything was rubbed down with some light machine oil to give it a coating… I keep meaning to get some spray on anti-rust like Balistol or similar, but keep forgetting.

Yeah, I had a bit of a chuckle at that one. I’m sure it was the cause of many a smutty joke in the workshop at the time.

Googling the name of the company brings up nothing but images of similar tools - 2-20 like this one, and then a 4-20 that seems to be more prevalent. I wonder if it was more of a trade mark rather than a company name.

I seem to recall making one of those as an apprentice. I dont know what happened to it so perhaps it didnt turn out as well as it should have but that does look familiar
