Great collections. Thank you for sharing them with us.
Unfortunately, I have had nothing but bad experiences with vintage Platignum. The ones I had were fragile and delicate. I found them difficult to repair* and never found them to be great writers?
I should point out that this was many years ago, and many of the pens I had back then came in job lots, so were never in the best of condition. My memory may be painting them worse than they were, but I went on to collect other brands and abandoned the Platignums.
I hope you have a better experience with them.
Your Stephens and Parker Victory collection is excellent.
Best wishes, CS
*I wonder if they were casein pens, which made the broken barrels difficult to repair?
