Nuair 29 balance

Thanks for reaching out. We should be able to help with these balances, but your photos only show the top nylon fitting. I'll also need to see the bottom fitting. If possible, please also measure the depth of that bottom fitting and write out what you get for me. 

Lastly, I think it would be best if we got a photo of that 29 HP33-41 stamp you gave. That's a very, very peculiar stamp and may need to be a custom order. A photo of the stamp will be necessary for research purposes. Thanks!
