Queensland 1st Sideface imperforate issues

These stamps are known imperforate but in order to be able to prove any imperforate copies are not fakes they would need to be on cover (best of luck) or a multiple. Stanley Gibbons 2012 catalog lists the imperforate issues as follows:

SG 128 ab 1d. reddish-brown die 2 wmk QW5 – a horizontal pair, no price given

SG 134 a 1d. reddish-brown die 1 wmk QW6 – imperforate between pair £1,100 used

SG 134 bb 1d. reddish-brown die 1 wmk QW6 – QOEENSLAND imperforate between pair £1,200 used

SG 135 ac 1d. dull orange die 1 wmk QW6 – QOEENSLAND imperforate between horizontal pair  used, no price given

SG 139 c 2d. bright blue die 1 wmk QW6 - imperforate between pair  mint £1,500

SG 141 a 4d. orange-yellow wmk QW6 - imperforate between horizontal pair  mint £6,500

SG 143 a 6d. yellow-green wmk QW6 - imperforate between pair no price given.

The 2006 Scott’s Specialized Catalogue lists the following, with some prices being given:

57 d 1d. rose red wmk and Q (68) imperforate
57 e 1d. rose red wmk and Q (68) vertical pair, imperforate horizontally $725 used
58 e 2d. gray blue wmk and Q (68) imperforate horizontally $1,100 mint

59 a 4d orange yellow wmk and Q (68) imperforate
60 a 6d yellow green wmk and Q (68) imperforate
Also a note that says"Nos. 59-60 exist imperf. vertically"

Robson Lowe (1962) notes the following all known imperforate vertically between pairs
62 1d reddish-brown Die 1 £6 used
63 1d reddish-brown Die 1 £7 used
67, 70, 71 listed but no price as "unknown to us." I assume that means they are aware of these stamps existing but have not seen them.

Going back through the historical record I find the following:

The Philatelic Record, January 1890, p. 8 notes that it has seen a horizontal pair of the 1d. deep vermillion (scarlet) hue without perforation between the two stamps (i.e., perf 12 but imperf at one side).

Charles Phillips writing in the Stanley Gibbons Monthly Journal 29 November 1902 p. 100 -101 noted that he had recently seen several superb specialised collections including some Queensland 1st Sideface imperforate issues, listed as follows:

The London Philatelist, December 1902, p. 286 lists the following:

The 1912 Stanley Gibbons lists no imperforate copies.

In the Australian Philatelist 7 June 1919, p. 167, it notes that: "Mr L. H. White has shown us a pair of the 2d. of 1879-80 Die 1., wmk 1st type Crown and Q, imperf. vertically but only between the two stamps. This is an interesting variety not before recorded. The pair is from an early printing." Presumably this example, SG 130, is now part of the L. H. White Collection in the State Library of New South Wales.

The 1940 Scott’s Standard Postage Catalogue lists the following, without any prices being given:

57 e 1d. rose red wmk and Q (68) imperforate horizontally

58 e 2d. gray blue wmk and Q (68) imperforate horizontally

59 b 4d orange yellow wmk and Q (68) imperforate vertically

60 b 6d yellow green wmk and Q (68) imperforate vertically
