Hello Pete:
I am in the same age group, turning 65 in February and have noticed that things that used to be quite simple are a bit more complex. Like Lance, I can't remember where I put my nice PE Bezels. So, I have to get some more. (Now if I can remember where I got them from). Your attitude towards this is a positive one, and you can still turn out great models without the extra super detailing. I have spent a lot of money on after market super detailing stuff only to put it away as it isn't worth the effort and it takes the fun out of it.
That being written, I am looking forward to seeing you progress through your Eindecker.
Best
Mark
