An antique National cash register key cover/hood and bracket that holds the model number plate. Brass. Made in Dayton, Ohio USA. I believe it is dated 1906 and fits models # 332, 333 and up.  However I am not expert and have not had an expert look at it. The last picture shows a complete register for reference it is not the same cover.
Shipping is correct it weighs 8 pounds with no packaging and it does not fit into any priority flat rate boxes.
I have other National cash register parts listed for sale.  I will combine shipping.
Thanks.
