Mark: Banks was only with SR for a very SHORT time but Raynor gave him full credit for the projects he work on with him - and there were many - too many to document here.
When Raynor died Charlie Banks had many more courses than you could image - plus to courses he lost because he was either not as a big a "name" as was his partner - Banks became a partner not too long after Raynor stole him from Hotchkiss.
Banks had little to do with the design at Fishers Island - but did complete the course, of course - same at Yale (but he was working there)
Then you bring up the issue of who gets proper credit etc..... well, probably at F/I and at Yale there was little left to do - same Yeamans Hall, although a few bunkerws there look supicously like Banks. But at Fox Chapel and Blue Mound there was a lot left to complete - they being up north and with Raynor dying in Jan 26 and work had come to a halt.
Raynor never saw ground broke at Lookout Mtn but he designed it without Banks - same with Waialae and Mid Pacific.
So where does the credit go? Hey, they were partners and I doubt if they really cared - I'm sure Raynor didn't from what I've been able to build of his (nearly non-existent) "profile."
Banks and to clean all these loose ends up before going out on his own. He was a bit more talented than most people think.
There were a lot of plans that were at courses that some clubs had built by others. Two quickly come to mind: Essex Fells here in NJ had a set of plans and they hired the Scottish pro at Upper Montclair CC to use as his guide - and this was about 3 or more years after Raynor died (Banks probably didn't even know of the plans although he was working nearby); there was Silver Spring CC in CT built by Robt White according to Banks plans after he died.
Not all really black and white - which is why it takes so long, complicated by Raynor who documented next to nothing.
Can you imagine rookie Banks in 1926? .... like, "Raynor - you died now - in the middle of all this" - - hah
I built an interesting Timeline of Events that shows the years they were working and where (to the best I could figure out). The activity during the years 1922 thru the time of Raynor's death was reaching hectic pace (as it was with all the archies, we can be sure) - but in the case of Raynor he was much more hands on than some of the others.
Most of the time the completion of a course is listed as ,,,,, Yale 1926 .... well the project lasted nearly 4 years with contacts a year or so before that - so it is not just one year for a course. Shoreacres spanned over WWI as did CC Fairfield, Shorecres goes on hold for the duration as does CCF but at CCF continue the massive landfill operation. Those course went on for about 6 to 8 years.
