Good morning, I am looking for a working TT-98 to replace the UGC-74/B in my GRC-142 teletype shelter, i would like to get it back to it's original all mechanical form factor.  I am willing to pay shipping or I may be at a hamfest or military show you are attending, etc.  Once a TT-98 is found I will have a nice working UGC-74/B for sale.
