RARE DTMF MOTOROLA HT220 UHF 462.275 PL SP MODEL MODAT

Description

up for your consideration is a used RARE UHF DTMF HT220 that includes the PL Circuit
this is also rare in that it is an SP model, SP stands for special production, you can see its reference on the model plate
this may also have some kind of signaling circuit, like MODAT, but not sure of that. there is a reference to code 2547/2745
in the 80s a reference like this might indicate MDC600/MDC1200 but being this was made in the 70s it could be MODAT
it might be some proprietary signaling that some power company used for signaling power distribution equipment
but it might not be anything, there is a reference to MON- RESET on the top near a button. i have seen MT500s with a button on the top for MODAT.
some HT220s didnt come with PL most didn't come with DTMF, so this has the best of both worlds :)
it needs contacts cleaning and possibly some restoration.
selling untested for restoration
see pics if you have questions ask. if you know what the SP references are, please let me know thanks.
