Windblown, your 1941 crinkle machine is most likely a 99-23 or 99-24. Same machine, but one is knee bar driven and one not. I have one; it's my avatar. It is cute. There's no K to this model if it's made in New Jersey. I found a manual online by doing a search using the model numbers (one manual for both models). There are usually a few on ebay for an astronomical price, and parts can be easily found. I use mine mainly for decoration, but it works great. Sewing machine oil every once in awhile applied in a light finish and rubbed off will keep it looking good. You should be able to get your light working. Because of its WWII origins, there is an historical significance to this machine and the crinkle finish that may make it easier for you to accept it's appearance---in my opinion you would be dishonoring this machine by hanging an ikea light on it (use one next to it if you must for functionality). Once you get it cleaned up you may love it more.
