I'd be combing the local scrap yards to try to save my original parts and maybe get some help on catching the thieves! Here, a scrap yard owner doesn't want to be implicated in receiving stolen merchandise, either knowingly or unknowingly!
You have a wonderful day. Best wishes. Deas Plant.
Hi, Links56
If you have a HOLT, as I understand things, it was likely built before April, 1925 'cos that's when Holt and Best 'got married'. I think everything built after that was branded, 'Caterpillar'. Sorry to hear that you have some light-fingered folks around your way. Might be an idea to get a 1/2 dozen junk yard dogs and chain them to it.
Just my 0.02.
