There seems to be a pair but one is made better that the other.

One has 6145 on the heal this is the better of the two.

The other does have some short of marking on the heal but unable to read it, this one also has a old chip at the toe and a hairline crack by the lace hole on the front (see picture) and is slightly bigger that the better one.

The better of the two does not have any chips and has more definition,  ie the stitching is more pronounced,  it is 6 ins long and from heal to top it is 2 ins high 

These were given to me in 1990 by and Irish lady and she had them for a long time before that,  I do not know the age.

They are quite tactile, I think ribbon must have been put i the hold as laces , I think the style is a Victorian shoe 

They do need a wash
