Early Crestworth light bulb question..

[Mr MaGoo]

Hi all, just picked up  an early Crestworth lamp on eBay and I am having to do a fluid change etc to get it up to speed.  Also want to pick up some light bulbs for this lamp.  Lamp is US wired and uses a

40watt, 120volt E-14 base light bulb..believe the Brits call them oven bulbs. Here is a pic, does anyone have a vendor that they use that sells these at a good price..just wondering..thanks again!

We call then golf ball bulbs and they are 40w.
