No its not easy, but were are only talking mid 70's here. There are many Wolverhampton employees about, some still working, but those from the NVT era? As for the economic climate, I remember queuing for bread in the 70's here in the UK, the daily power cuts, and the prolonged bin strikes. As for the machinery of the time, much of it still in use, some is still good, some worn out. Some foundry's are still hand tamping sand and gassing the melts to compensate for poor pattern designs that are left over from the old days.
Those decision makers from that time had a love hate relationship with the government, they took the hand outs for trade and hated the government for supporting or doing nothing to clamp down on the unions.
The Commando was an excellent bike, the early bikes being the best, the MK3 a pile of crap (I have 2) this reflects the demise at the time. Mind you with careful and sensible rebuild the MK3 is excellent. Even in the same camp quality varied, look at a P11 outer primary cover and and an early Commando primary chaincase, one made by the AMC side the other by Norton, the P11 is far better.
Had the motorcycle press at the time and in the late 60's stopped pampering and blowing smoke up the backsides of the remaining bosses of what was left of the UK motorcycle history and told the truth about the Japanese bikes and UK bikes at the time, something could have been done - the drawings were on the boards and some designs nearly ready. Case in points are the rotary valve for two strokes - an attitude of it was too expensive and would never catch on, and an additional cylinder for BSA/Triumph triple are ideas that stopped short of creating new openings.
There is report in one of the magazines, about an AS90 thing - it is tested from London to Portsmouth and back, rides without fault throughout and still gets slated, the journo should have been shot for this report, the bike was far better than the Bantam 175 kicking about at the time - the same dodgy decision makers indirectly paying his wages it seems, maybe some of the testers could explain if any are still about.
