I checked on the nozzles you requested and unfortunately I couldn't find any old or reserve nozzles to send you. We typically trade them in when we purchase new ones and/or use the old ones for our recruit training academy.
I don't know why it's take so long. We us electronic machines to sort make and if you don't
address the envelope right the machines will eject the letter and they would do the sorting by hand. Depending on who got the envelope they may just send it back thinking that I sent it.Give me your address and I will send you one of our patchs and you will see how and envelope should be address.
