I would usually use flash for this and ensure that the reflections from it bounced well out of the camera view and then used perspective correction software plus mid contrast tone mapping and sharpening to get round the looking through glass effect.
I decided to take a couple without flash out of curiosity and wondered if anyone had any further thoughts on getting round the problems. The shots were taken in an early water powered needle polishing mill that managed to process over 1 million a week. 2 polishes for ordinary and 3 for best quality. They made needles for all sorts of sewing. The best display wasn't suitably placed for a shot.. The mill later turned to fishing hooks and early on made the basic item by hand. The equipment was interesting - hand punches for the eyes. Redditch was also famous for spring manufacture.

The perspective correction is odd. I suspect that the frame isn't square - it's over 100 years old. They were pretty mechanised by then.

This one had to be taken straight on as it was in a stairwell. No chance of using on camera flash.
