Help Identifying Frame markings

[CaffeineRacer]

So I'm in the process of scrapping all the rust and crud off the frame and hog troughs of my 1982 Avanti so I can seal it all up with some Por15. After removing the 30+ years of grime I found some writing painted on the frame's x-member. I would love to figure out what it said originally so I can replicate it over the paint. Call me silly, but the little touches or originality are what I love about the intimacy of old cars. They remind you that an actual person spent time carefully assembling each piece of the vehicle.

So far I think I can make out the word "BUNDLER" "BY" and the number "3".

Anyway, here are some photos. Any on have any idea what it may have said originally? The car is RQB3526.
