eBay shows item # 310101443233 as "SCANTRONIC 09823UK-00. NVM chips (pack of 9) for 07200" £10.50 + £2 P&P = £12.50
It does not specifically say for 9100 / MX48, but how many different NVM 8 pin chips did scantronic use. It might be worth contacting the seller to see if they are appropriate.

It went missing after a visit from an emergency alarm engineer who said the system was unserviceable and needed replacing.

Can I ask why you would want this NVM, I assume you already have one in a panel.
