Precat gauges - who made them?

[saxon]

Seems people suggest both WTB and Stewart Warner made them - anybody know? Reason for asking is my precat handbook suggests 5W instrument bulbs should be fitted and my riff came with 3W ones (which probably explains why they're so bloody dim!!) I just wanted to check that 5W would be OK before fitting them and burning anything!

Your gauges are Stewart Warner like mine and I put 5W green tinted bulbs in mine which I think look brighter than using the little green caps over white bulbs. Hope that helps.
