Vax Carpet Cleaner - Spares or repairs (Bolton CA16)

Vax Rapide Ultra carpet cleaner. This was working well, but the clip which holds the dirty water receiver in place broke. The broken clip and one of the broken lugs are shown and will be included with the machine. Without this clip the receiver tank does not lock in place and the machine does not suck the cleaning solution out of the carpet (it is quite good at making the carpet wet!). All I could find on the internet is that the part is no longer manufactured. Someone with a 3D scanner and printer could probably make one. (I have just searched again (17th March) and there is one on eBay for £19.99)
