Jamaica Kg VI Pictorial Varieties

I am creating some custom pages for the KGVI pictorial perforation varieties. This will supplement my Steiner pages.

I had two questions on the 5sh issues.
1. There is a reference to "line". The issue has a high car price but curious what "line" means such as line performation?
2. Is Scott 127a the same as SG 132ba or just two different varieties. I doubt I would add a space. Scott mentions bluish paper but cannot find any reference elsewhere.

Once again some inconsistency in listings. I would prefer the first variety be issued the major number and the subsequent varieties be listed as suffix. For Scott, the major number means a spot on an album page.

Any Help?

Angore,

Maybe this article clarifies things.

It looks like the line perforation issue was discovered (or listed) after Rod's catalogue was published. It looks like the comb perforated gauge 13 stamps in the shades of 1949 and 1950 are now SG132b and 132ba, respectively. The C-site that is censored here uses those numbers and mentions blued paper for the 1950 stamp. However, I sometimes get the impression the site just copies Scott. And it does suggest Scott 127a is a bluish paper issue, being SG132ba.

It looks like the original perf. 14 1938 issue was perforated with a line perforator in 1941. This may now be SG132a.

Maybe someone with a SG Commonwealth catalogue issue in the 1990s or later can confirm this.

SG Commonwealth & British Empire Stamps 1840-1970

SG 132a 5s. a. Perf 14, line (1941)

No. 132a shows the emergency use of a line perforation machine, giving an irregular gauge of 14-14.15, after the De La Rue works were damaged in December 1940. The normal comb measures 13.8 x 13.7.

Thanks for confirming line means line perforator.
