@Masgrimes I have been so fortunate in that I invested in a box of vintage ones about 15 years ago. 
So I haven’t purchased any more recently. Funny though - I haven’t used them for some time so I will have to dig them out. 
Ah, yes, invested is the right word. A good buy, but closer to 6 yrs., 9 months ago--time does indeed fly but not (thankfully) that quickly. Trot those boys out
@Erica McPhee , and give 'em a workout. They're dying to be used. Your work is so good now, you can really get the most out of them.
Anyone (
@Cyril Jayant ,
@Mark T ,
@JanisTX ) who would like to try one, just pm me your current address and I'll send you one, no cost. As
@Ken Fraser said 7 years ago, given my age, I probably have enough to see me through.
As to whether the new ones are less good than the old ones, I can't say,
@Masgrimes , as I have only the old ones, but if you would like a few old ones to compare, let me know (I have your address, of course).
