I have a Lambert and need advice

My advice...? Ride it, you'll love it. A great lightweight bike that really stands up against many modern bikes.

Don't do anything to it except a rub over with an oily cloth, maybe change the chain for a new one, maybe new tyres. Keep it exactly like that.

BUT...put a magnet on the fork, it's probably a 'death fork', and as such many people will say do not ride it under any circumstances. Many people do ride them, but the logic is that if they were going to snap, they would have done so by now. IF that one hasn't been ridden since the 70's then that logic doesn't really work.

You can get a new fork and be 100% confident when you go for a ride.

In terms of value in $'s...dont get too excited, you can't retire on the proceeds. They go from anywhere between $50-$200, but the parts are generally worth $150 . Not hugely rare , but that is a very old one and in very nice condition..

If you were in the UK and were dead set on not ridding it, then I'd say someone would come and buy it within a few weeks or so. Not so sure in US where the distances are bigger?

Thanks for posting photos , great bike, and lovely colour. By the way, I'm 5'8" and ride that size frame (23.5" by the looks of it)

If you search around on this forum you will find lots of references.

PS - love the photo's - how about some of the chainset (with those iconic portholes) , and the rear derailleur mechanism?  
pps What name is on the wheel hubs , and what are the pedals?

Can you Dad  give any more of the history of it?
