cblinton: Aviation Consumer has published a number of articles on the high inflight structural failure rate of early Bonanzas, especially pre-1949 'straight' 35s with the thin wing skins and some of the later models without nose ribs in the stabiliser, though much structural beefing up had been done before your M35 was built. I believe I have the articles 'somewhere', and if you are interested please PM me with your address and I'll dig them out and copy to you. I think I also have a picture of your Bonanza way back in 1960 when it brand-new and wore an Irish registration.
