Woody Bartelt of Aero Electric fame has long been a major supplier of replica model engines and parts. The list of replica engines which he made available over the years is quite mouth-watering, and the catalogue of parts on offer is truly amazing. Woody did not confine himself to American engines - one of his latter-day ventures was a series of the parts typically required to restore the popular English FROG 500. Having bought quite a few parts from Woody myself, I can attest to the fact that their quality is uniformly high - often better than the originals, in fact!
As regular readers of my articles will be aware, I myself bought a number of Woody's replicas over the years, most of which have been tested by me and found to be excellent engines which are very faithful to the originals. The Ball 60, Baab-Fox 60 and Bungay High-Speed 600 are examples which have already been covered in separate articles either here or on "Model Engine News" (MEN), and there will be others as time goes by.
Sadly, Woody passed away in April 2018. As of that time, his son John stated his intention to continue to supply parts from existing stocks, but he was only able to devote one day a week to this activity. Patience is therefore greatly appreciated.
Woody also generally had a good list of original engines for sale at any given time. Check out his excellent web-site for the current listings.
