BTW, my other pass-time ins cycling. So I've been looking at these:
Its the BSA paratrooper bicycle, they dropped them with the troops so they could move to their objective faster. They come apart in the middle for transportation. Unfortunately they cost a fortune but one day I might afford the Pashley replica and attach fake connectors to the tubes
They were apparently a very common choice of bike in certain areas of Holland in the late 40's-50's, can't think why
