The answer, of course, is on crutches.
It is only by sheer co-incidence that TO brought these critters inside after I had looked at
Andrew's Sunday Selections where I
learned that Prince Henry's Hospital closed in 1991.
There was some point to the application of WD40 to rusty nuts and subsequent adjustment of crutch height – TO wished to demonstrate what is required for the proper use of crutches. There was even some point to the demonstration but, yawn, let's move on to something far more interesting [as if it were possible].
No, your first impression is not correct. TO is not a compulsive hoarder – she simply likes reminders of momentous events in her life. These crutches were used by her good self shortly after the great car crash of 1964. She assures me that she did not keep this particular pair of crutches as souvenirs, nor did she keep them because she believed they might come in handy one day; sometimes she just "forgets" to return things.
In any case, I must admit that of all the crap in all the sheds in all the backyards in
this little pair of crutches has been
useful. They've been loaned and returned many times over in the ten years I
have been sharing my life with TO and her crap.
How much of that manufacturing output, I wonder, has consisted of wooden crutches? I do believe demand might have been very high from, say, the beginning of the 20th Century and for quite some decades after.
