I did just what you don't want to do - small wall (as I needed to bring the floor height up), then simply fitted uPVC panels - solid panels to mid-height, double glazed above, opening door and a half to the front.
thickness of the pillars would allow you to add internal insulation if needed.

My Meccano set of the same type is in the loft in an old biscuit tin - and looks like the owner of that one lost all the original black screws and hex nuts too, same as I did.
I bought some maybe 20 yrs ago when working in the USA . . . while out of the packet I think I've used two, twice . . .
Cars, even my Lancia, don't rust as they used to :D
I suspect there is a missing "e", much as I suspect you really meant an "f", rather than it being required as an extra warning to following drivers :laughing:
If you aren't using it, but storing it, stockaking it every time, it's taking up space you could use for stuff you do want, the time of employees you want doing paying work, therefore it's costing money several times over - so get rid. Most painless way to get rid, avoid prolonged sales efforts...

This apparently was just after...
As a design engineer I can see why they did that - it allows the use of all the stock of existing uprights with the new calipers, it doesn't require a new part number for new uprights, with the chance the right side could be the old one, the left the new . . it means new calipers will fit...
Yes, nominal bore of 1" schedule 40 pipe is 1".
Then outer diameter stays the same and different schedules use different wall thickness, so changing the bore.
I was amused the first time I worked in Germany to discover DIN pipe was just BSP rounded to a metric number :D
