Thank you all for your help
I have an update on his most riveting of niche groundsman topics
* Ransome Gangs are off to Crewkerne Horticultural Society for a restoration - they collect & return (for a small charge) they will assess & quote for the full restoration but standard service & regrind is £132 per unit plus parts and VAT
* Auto Roller only deal with their own brand rollers so cannot help - but Poweroll have been superb, just trying to figure out exactly what we do but I think we have a plan - we will rent one of their rollers for £95pw plus VAT whilst ours is either saved or put to sleep
If anyone is still reading this I will update with photos and progress as it happens
