Old Stanley Gibbons Instanta Perforation Gauges

Does anyone collect old Stanley Gibbons INSTANTA perforation gauges?

For many years, the first such issued perforation gauge which only went up to perforation 15 was very hard to find in that I only found one in twenty years. Now, I have been able to suddenly find several of them in just the last year.

This may be due to collectors that had them either now selling their collections or their relatives selling their collections after they have just recently passed away.

Regency Superior sells one for $9.95. Is that the same one you are talking about?

Raided an old box to find my old accessories. Cannot remember if the Instanta actually was that yelow-ish color or old age had crept up on it. In a attempt to sound like Spinal Tap... These go up to 18
Never actually used the Thirkel all that much and cannot believe the color guide is still accurate after all these years.

My ancient Instanta is yellowed but I don't think it is age. I have also had clear ones too.

The best perf gauge IMHO.
