As the title suggests, I seems to have made my own life rather difficult. Having yesterday gone to the Woking exhibition, I picked up a Mk1 SLSTP sleeper like new for £21. The catch being that, whilst trying to figure out its uses, I have got the 'wrong' sort of sleeper. Not quite realising that there were 1st class and 2nd class sleepers (instead thinking that they were a supplementary upgrade on a 1st class service), I got a 2nd class Mk1, needing, in fact, a 1st class one. So, here's are the issues: I have accidentally limited myself to the months-long window between the withdrawal of the Fowler 4F and the introduction of the Inter-City brand. I have purchased the wrong type of Mk1 sleeper Would anyone have any suggestions for remedying this considering that I am A) sub-par with using transfers and other delicate jobs and B) unlikely to find too many prototype photos? P.S. Please move to a different category if necessary.
