Valve spring compressor

Having lent my antique valve spring compressor one too many times - it’s gone missing.
Can anyone point me in the right direction to buy another one that’s good for Guzzis?
I have tried/borrowed a few new ones and they’re all rubbish/ not big enough for our heads…

This any good? Ebay item no.392000853809

We’d be getting ripped off by dodgy ads in Exchange & Mart, as what often happened in the old days.

Ah fond memories, not, and loot!
