Anchor silks - Old numbers to current ones

I have a lot of old Anchor silks which I want to be able to convert to DMC silk numbers. Is there any way of finding a conversion chart for this. I understand the Anchor silks were renumbered in the 1970s.

How to convert Anchor floss numbers from early 50's to todays Anchor or DMC

I wish to complete a wonderful embroidery my mother started in the 1950's. It is a very realistic picture of a pheasant with a border of different leaves and berries. I have the instructions in a magazine , and a jumble of threads, but many have lost their numbers, and there is no colour illustration. How can I find a conversion key? as I understand Anchor numbers changed in the 70's. Exact match is not critical.

Thank you.

Can I get a chart that converts Anchor embroidery threads to DMC embroidery thread numbers. I have all DMC threads but a chart I want to cross stitch is in Anchor.
