What size seat post diameter? If you don't have calipers, any spare seatposts to sample in the frame to check the size?
Even easier way to identify bb type- look at the threads, both going the same direction? Not English. One side going opposite direction of the other? English.
Cool bike, we're it mine, I'd find some rivnuts to use the holes in the seattube (and keep an eye on them) rather than try to hide them.
