[p5b401]

The 401 had a couple of different front bumper fixings. Both had fairings although they weren't that deep. My car was a resto project and came stripped down with a very mangled fairing. A friends '53 403 had no fairing and he tells me it was original spec.
Perhaps in Bristols parts juggling there were some configurations without a fairing but I suspect that as a thin low hanging aluminium part, it is likely they got damaged frequently.
