here that says on the lower part of the dial,LONG RANGE HIGH
SELECTIVITY.MODEL NO.7-2880B

That's a Super 1, mine is a 7-2880A and I think the only noticeable
difference is that yours
has an external antenna connection. I've never had mine apart but have heard
that it's real easy to damage that on/off switch when separating the case
during disassembly. RM~
