Got one of our charity shops out of a bit of computer bother last week. Found a box of glass on my doorstep this morning as a thank you. That was sweet of them.
This lot particularly interests me. I think they might be related.
First of all 6 small-bowled, stemmed glasses, 17 cm tall.
The style looks Germanic, or maybe Czech. They are top quality, irridescent all over, and appear to have been "carnivalled" in marigold before being cut. The pattern is 3 vertical lines plus a vertical "wheat ear", repeated 3 times.

Also a candle-holder, 15cm tall. Top quality again. The bowl, only, is irridescent in the same way as the glasses. It is cut through with a pattern of small flowers.

On the base is this mark, acid- or sand-etched.

It might say JR. Couldn't be Riedel, surely? I have a few wine glasses that I've picked up over the years. They all are marked "Riedel".
If anyone knows the maker and age, it'd be much appreciated.
