Apollo box spanner.
Size = 7/16 x 1/2W
5" length.
These spanners are new old stock which has come from an old motorcycle shop tidy up. The spanners are unused just tired and a bit grubby from being in storage for so long.
The price is for ONE box spanner. You will receive ONE from the pile in the photo.
I usually post with EVRI as it is trackable.
