I double checked the wiring diagrams in the '51 truck service manual for both '48-'49 and '50-'51 and they don't show a horn relay on either.
They show a 14 gauge wire running from the hot side of the ammeter to the horn and then another 14 gauge wire running to the horn button.
The horn was gone on my '49 when I got it and I just went ahead and put a relay in it when I went to 12 volts. I'd always assumed that it had one originally too.
'38 Chevy 1-1/2 ton
'49 Chevy 1/2 ton
'54 Chevy 6400 2 ton
'55.2 GMC 3/4 ton
'56 GMC 1-ton
