I sent some photos of this to a Dutch dealer specialising in Leerdam, with all the dimensions etc. and he has confirmed it is from Floris Meydam for Leerdam c. 1954. So, hopefully that is the firm conclusion??? Over to you Ivo. Regards Emmi
P.S. The colour in the flesh is not at all brownish, it has a blueish/greyish tinge. Emmi
