Need to identify and replace relay coil

After some help on this forum I've identified the problem with my Gottlieb 1978 Cleopatra EM. The Game Over relay has a burned out coil. Pictures attached.
My next challenge is finding a replacement coil! The part number on the plastic section (D15341) is apparently NOT the part number for the coil. The part number for the coil would be on the paper wrapping - but that's burned off!
Can you help? Where can I get a replacement coil unit to screw back in beneath the switch leaf-spring stack? The switches seem fine. Just need a new coil.
Thanks!

OK, I was a bit slow. I dismantled another similar relay to find the coil part number. A9735. Simple really.
I'd still appreciate a steer on anywhere in the UK that stocks these. I can only find a US supplier.

Hi, Sim,

A word of warning; simply a similar sized relay coil may not be right. AIR, there are two common Gottlieb relay coils like that, '9735' and '9738', and I've a faint recollection that a Game Over relay uses the latter, which is rated for long-term use (i.e. whenever the machine is in Game Over mode).

If you have a schematic drawing for the machine, the coils/relays used are listed on it

You won't find these in the UK.
PBR USA are only supplier.
GTB A9736 here.

Double check schematic to get correct coil.
I might have a spare GTB A9735 I can sell. Ordering from PBR is a complete pain as have to send cash or get someone in USA to send a cheque and then expensive postage and 20% VAT. Oh and the lovely £9 handling fee just caps it all off!
 
I think the game over relay should be a-9740. I've added this to my shop for you.

In the meantime, I've looked at a spare Gottlieb motor panel, and what seems to be the G/O relay ('Q' in that particular game) was indeed an A-9740. A 9735 certainly isn't the one for this, it's used for 'pulsed' relays such as point scoring.
