Carl Zeiss Jena Icarette Compur. No. 724738, Tessar 1-45, f=7.5cm, ICA A-G. From the serial number I have located on it this iconic folding camera was made sometime between 1929 to 1931. Has been in the family from new. I have not tested it! It opens nicely, the bellows seem to look in excellent condition. Can't comment on the lens etc in afraid. The case shows age related wear here and there. The same can be said about the original leather carry case it's in. A bit of the surface leather missing from one side of the strap. Combined weight is 538gms.
