[78-L] Majestic Duraflex

[Han Enderman]

Were Majestic Duraflex issues promo pressings for broadcast, 
or were they also available in shops?
Lowest Duraflex nrs known to me are 1050 (Prima) & 1060 (Lunceford).
Last known issue 1226 (Guarnieri), which is somewhere near the end of this 1000 series.

The Duraflex label also occurs in the 7000 & 11000 series.

Ty lists Majestic 1001-1271, but with many gaps after 1229.
The last 2 images I have are 1231 (Eddy Howard) & 1271 (Rose Murphy).
Any explanation for these gaps and the rarity of the last cat.nrs ?
