National Optronics 3B Blocker and 4T tracer for sale

[doyleopt]

I am selling a 3b blocker and a 4t tracer with all the attachments and manuals included. Everything does work and I can certainly ship but would be able to meet someone within 50 miles of 60093. The photos should be self explanatory but if there are any questions please let me know and I will answer them to the best of my knowledge. They were working when last in service (6 months ago). Asking $450 for the tracer and $2500 for the blocker but will listen to offers.Attachment 11487Attachment 11488
