The detail about these being harvested as parts donors for Speedmster is kinda wild. I love how you call out the lug styles - the straight lugs on the 105.005 really do look awkard compared to the beefy ones on earlier models. My dad used to collect vintage chronos and always said the best finds were the overlooked references, so this guide hits home for me.
Are these mostly radium lume? Probably, right?
mostly radium, you'll see some tritium towards the last few references (note the "T Swiss" signatures below 6 o'clock)
