In looking for something else I came across this thread, and thought I'd add a few notes as ive been researching these aircraft for a number of years now, so excuse the lateness of my post.
To start with, there were actually 23 Lancaster's converted, the missing one from the initial list being ED765, which was the first converted, serving as a test aircraft before joining 617 Squadron in early July 1943 where it was coded AJ-M, replacing the original AJ - M (ED925) which had been lost on the dams raid. ED765 only lasted a month before it was lost in a training accident. Although some were damaged on the dams raid, none were reconverted at the time to standard configuration. The '/G' suffix was (as mentioned) to signify a guard was needed as special equipment was aboard, but this usually referred to trials aircraft. The G was removed on 617 as the aircraft and base were routinely quarded.
Of the others, several were converted to allow 617 Squadron to use them in training in late 1943. It seems 617 converted them a bit more than they were given permission for and they were almost fully converted, and brought on line as standard aircraft, complete with new KC coding (the 'Dambuster' configured aircraft kept the AJ coding). Contrary to what has been written, this included bomb doors and mid upper turrets. I have proof of the latter, having excavated ED825 (which had become KC - E before being lost in December 1943). The team found part of the mid-upper turret.
The problem lay in the fact that another dams operation was on the cards right up until the end of the war, and as such the aircraft were required at short notice. At the same time, they were becoming hard to maintain and were rarely flown. So some were retained on 617 Squadron as standard aircraft for practise flights, others flown on operations. In the spring of 1944, many of the survivors were flown over to 106 squadron, who used them for transport, training and general hack aircraft. others were used at 54 Base for smoke, altitude and other trials and tests.
There is mention of Gibson's AJ -G at Metheringham. This was in fact Maltby's ED906, which had been converted to standard and given the codes KC - J, before reconversion back to Dambuster configuration with the code AJ - G. Gibson's original ED932 was reconverted to standard in late 1943 and given the code KC - V, before being used in drogue and other trials at 54 Base. As the end of the war approached, all the survivors were reconverted back to dams configuration before being placed in storage, as an order was received they were to be on 14 days notice for another dams raid.
At the end of the war, as part of 'Operation Wastage' (the disposal of surplus bombs) around fifty Upkeep mines were found to survive, so three aircraft were taken out of storage and made airworthy for the task (Operation Guzzle), which used crews from 9, 61, 101 and 617 Squadron's. As has been noted these were ED906, 909 and 932. I have photographs of all three at this time (in fact, the original photograph posted showing ED906 is owned by me). After 'Guzzle' was complete, the three were scrapped at Scampton, but not before all the special equipment was removed, as it was still considered secret.
So the story of the 23 is a complex one involving conversion and reconversion, later operations, trials, transport, and a lot of wrangling up high over their use and future.
