Parts for Frem Rojle Roundette Table ???

I picked up a Hans Olsen Frem Rojle Roundette Table and was so happy until I realized that it was missing 2 metal threaded dowels which connects the leg to the table. I have tried all the local hardware stores but they do not carry metric parts.

35mm x 11mm with 6mm threaded hole

I don’t know where or what websites sell this item.

I would be very grateful for some help!!!
