Actually, the first train I can catch arrives at 13:16 (tack on another 30 minutes for me to drop my stuff off) which means I won't be there and ready until 2pm, but then I have to catch the 1830 train from New Street back up North (so I need to be at NS to go down to Selly Oak aby 1730).
Alternatively I could just skip going to drop my stuff off and just carry it with me, everything fits in my stilt bag and I've carried it before, so I guess I'll do that.
So if someone could meet me at NS around 1316 that'd be great.
