Here is a Philips 45 RPM of Daniel Barenboim playing J.C. Bach's sonata in Bb-major opus 17 nr 6. It's from his earliest recording session, 1954.
This is the "A" side. The "B" side, with the third movement of the J.C.Bach sonata can be found at:

I de-clicked and eq-ed the record myself.
For three years I have a website, where I post "out-of-copyright" (in the Netherlands)
classical lp's and 78rpm's. It is updated every Friday:
