Ebay & Amazon are the perfect platform for shysters & snake oil salesmen .
You have no idea who you are dealing with and even less of an idea where they cource heir parts from.
With tinwear it is all bespoke.
You send them your money and whoever banks the cash puts an order on one of the "tinsmiths" to whip them up a tank for you.
Most are paid a starvation rate for this work so these are made at home. after work often from some scrap stee; supplied by the vendor
In many cases all the tinsmith has to work from is photo of what it is supposed to look like.
The idea that there are small factories is total rubbish, most are made from home out the front in the street in the dirt.
Endless stories of girder forks falling apart the first time they are used.
I for one bough a rear stand for the M20 from a local vendor which was made ( and is use that word very loosely ) in India
First strange thing is the bolts were Unified pipe thread , not CEI.
I put it on at the BSA international Halls Creek
So it did the first run ( 3 lifts onto the stand ) OK
It did the second , long run ( 9 lifts onto the stand ) OK
It did the third run ( 3 lifts onto the stand ) OK
On the 4th it fell apart & I meaan literally broke into 6 pieses as the bike was being lifted onto the stand for the first time.
So I think that would be about 400km all up
These stands are still being sold and people are still having them fall apart so their bikes fall over .
Only problem was I had it for year before fitting and the vendor had closed down , possibly to avaoid being sued.
So if you buy any part from India , make sure it is unpainted because that would have allowed me to see the rear stand ends were made from 4 pieces of steel tacked with a tig then filled with bronze which did not take then puttied ofe, smoothed down & painted so it looked like the ends were either forged or cast
I bougn some gearbox bushes only to find they had been cast into a smnd mould using the original finished machined bush as the pattern
Needless to say they got crushed & tossed strait into the copper scrap bin.
There have been several batches of counter shaft sprockets where the splines are cut wrong so they won't fit
And to top it off I have 4 rear QD brak e drums where the drum is not concentric to the mounting bolts or the drive pins & mounting bolts are not spaced equidistant or the bolt holes are counter shunk in place of being counter bored.
