Cast zinc alloy Essex chain stitch sewing machine c1946-1956

An Essex chain stitch machine, made between 1946 and 1956

It is very well made.

It has the handle shank but is missing the revolving grip (does not affect operation).

Dimensions: Ply base 22.5cms x 16cms x 19.5cms high

Weight: 1.4kgs

Condition: It appears to be in full working order. 
Note the screw retaining the needle is missing (I’m sure one could be easily fitted, as the thread is probably a standard thread).
