Need a replacement

That is a peculiar stamp, but we still may be able to supply this balance for you. Before we go any further though I would like you to remove an undamaged version of this balance and show me a clear picture of the top fitting and bottom fitting. 

I would also like you to tell me the depth of the bottom fitting; if you were to imagine that it's a shoe, I need to know the heel-to-toe measurement. 

Finally, how many did you need altogether?

Thanks in advance!
