Quite agree but was asked where you can get nickel silver tube from and MS seem to be the only supplier. Googling N/S tube brings up a number of companies but when followed up none can supply tube.
I have an order just in with them so will report on current pricing when I have it.
Prices as of 18 months ago were

Minimum quantity was 4 lengths but sizes can be mixed.
Buying a larger quantity would reduce the relative postage costs. It would also be possible to make up an order by going in with others which would share these costs so long as the people concerned lived close enough to each other not to negate any savings.
As regards my own sets - mostly I make up the tube to suit from 22g (0.8mm) sheet. I have a small rolling machine that works well on everything 11/16"OD and above - 1/2" to 5/8" are spun up on a mandrel and for smaller sizes they are rolled then pushed through a die using a 2 ton arbour press. For this latter an internal rod matching the finished ID is needed to keep the tube straight. Most of these will be parallel but for the long ferrules on the sliding parts of drones they are tapered.
The bending rolls I use are by Cherry Scale Models and have given good service since 1980
