Cooling fan balance weight

Anyone got a spare one of these curved fan balance weights lying about? I'm missing one from a Herald engine fan but I know they were used on other contemporary models of the time too. I thought I'd sourced one online a few days back but it's massive, far too large for the Herald fan, so can't find a source. Original part number of ours is (I think) 38665. All tips and pointers appreciated, or if you have one PM me. Thanks in advance!

Roger - it looks to be about 3 1/4 inches (it's a strange optical effect that when I line it up by eye it's 3 and a quarter but when I photograph it, it looks to be shorter at either end and so closer to 3 and an eighth)

(The silver one is one I bought recently after being assured they were all the same, it's from a Jaguar / Daimler)

me i would fit a plastic yellow fan better air CFM and much quieter , doesnt need balancing being so much lighter ..less mass 

and if buying or winning one how would you know the positioning  pin hole to correct the balance will be anywhere near whats actually needed

Plastic? Yuck. I'd fit a metal Herald one long before that.

In any case, it was because I was asked if I had anything that required balancing, to test out a machine, and want to see if we can make it work on fans... :)

Spent the last two hours trying to find a brass accelerator jet from a Solex carb; like you I can see it in the bottom of a box of bits... but just not the actual box of bits. It's holding up the entire operation, too... :)

 

Update: just found it in a box of electrical bits. Logical, really.
