I got this yesterday, I know it's a Collins, but what model is it?
Thanks!

P.S. - I need a nameplate if anyone's got a spare!

51J-3 or R-388

What's the difference?

R-388 is the military version and has a slightly different antenna input circuit.

R-388 will have military inspection stamps somewhere (generally) and most are coated with MFP varnish inside. Nameplates are often missing on the R-388, evidently because they were sold by hams who got them via the MARS program and were not supposed to dispose of them.

Eric:

Here's a page with some interesting articles on the author's experiences in restoring R-388s:

Note the spot above the dial scale. where it says 5673, that is where the name plate should be.

Think this is a R-388

R-388/URR
From the serial number it is probably Signal Corps contract 3357-PHILA-52 with an MFP date of 12/52
The ID tag would look like this one -
