I have been remiss in posting this. I will make amends for that now. I received these from my Dad at Christmas. I had been wanting one of each, but the tool money has been earmarked for other things, and will be for a while to come. But Dad came through.
Attachment 41956 The small caliper is a Santo No. 3005 5" It is in bad need of a good cleaning. I can get it to slide, but I have to force it. Can anyone tell me how it comes apart? Or should I just immerse it in WD40 for a while and then work it back and forth?
The larger one is a 9" Nippon Seiki. It appears to be newer, or at least well kept. Dad could have purchased this here in the states, or when he was in Japan while in the service during the Korean War. I need to ask him. I was too excited when he handed them to me to even think about questions!! Here's a closer look: Attachment 41955
The two micrometers are interesting. The small one is by the Lufkin Rule Co. with a patent date of Aug 1, 1922. Most likely, this was my Grandpa's. He was a civil engineer that worked for the Oklahoma Highway Department for many years. Had quit and opened a Redi Mix Concrete plant with some partners long before I was around. I remember seeing his drafting table and tools in the basement of their house when I was growing up. Sure wish I could have gotten those!!
The large mic is from Millers Falls Co and is a No.701R. Both of these are in pretty good shape. Attachment 41954
I've already put the large caliper into use once. It will be nice having these around the shop. Thanks for looking in!! Jim.
