It's a shame Fluke meters can't talk. I suppose we'll never know what fate befell this poor meter.
With regard to fuses, anything associated with the Fluke brand sold by mainstream suppliers tends to carry a price premium so I last bought some from here:

I'll have another rummage through the spares box to see if I can come up with anything suitable to help with the repair and will check for spare fuses at the same time. I'll send a PM if I have any success.
