[Closed] Mudguards for Older Islabikes

We picked up a SH Beinn 20 for Mat-ette's Christmas present, without any of the accessories (it was in great condition and the requesite pink). It doesn't have mudguards or a kick-stand though, I figured I'd be able to buy something aftermarket. It's a Beinn 20S one model back from current (May'16 - Jul'19) I believe.

I was going to order up some accessories but I'm a bit hesitant on seeing that Islabikes say that the mudguards & stands for current models don't fit older models. I got in touch with them to ask why and got answers I'm not that convinced by:

mudguards:

the attachment points have moved on the seatstay bridge. Rather than being threaded through the mudguard into the frame, the mudguard has a metal bridge on it that is affixed to the seatstay bridge with a m5 screw.

kickstand:

With our current range of propstands the clamp type remains the same but due to component and frame changes are not compatible with your bike.

They recommended I visit a good local bike shop who will have suitable accessories for a 20" bike. As a side note this rankled with me quite a bit, a web only bike shop telling people they should go and get aftermarket support for their products from physical shops. I'm sure it's the low margin awkward work they are crying out for. Also how many places in the UK actually have bike shops that carry stock for something like this? I'm sure shops would happily order in parts to see if they fit but I can do that myself! I know it's a hassle for Islabikes to deal with legacy components like this but not doing so seems to fly in the face of their ethical credentials (supporting the circular economy/extending the usable life of their products).

Has anyone on here tackled this quandry? Or got any recomendations on compatible components I can buy? (I'm after proper full coverage mudguards). I'm quite tempted just to order up some from Islabikes and see if they will work.
