Given the distributor info on the labels, I'd classify it as 'US' as well.Comment by MicSmith:
Does this qualify as a UK single? My understanding is that this single was pressed for inclusion in 200g copies of UP (the standard UK release was 180g) and the 200g edition was effectively an import from the US. The single was eventually made available separately but again I thought this was a technically a US release. Certainly when I ordered a copy through HMV in the UK they couldn't get it and I ended up getting a copy off eBay at least a couple of years later but can't recall the location of the seller. This was in 2012 I think.
Thanks for the scan of this issue which I do not own. However I would suggest this copy is the second version of DIY issued in September 1978 as the "May 1978" release (which possibly came out in June in the States) was backed with Perspective not Mother of Violence. Actually the only copy I have ever seen of this release with a proper b side is Canadian, so perhaps US copies are all promos with Mono/Stereo sides?
Oddly though the catalogue numbers (3479) appear to be identical for each version.....although that with Perspective is suffixed (ST-A-35066), whereas the later pressing is (ST-A-35067)
I bought the DIY 7" the day after release from my then local record store (Mike Lloyd Music) and it was the Irish pressing with purple label in picture sleeve. As others have pointed out this was far more common than the UK pressed copy with silver label and Irish pressings were used in the UK for other Charisma releases that year (e.g. Genesis' Many Too Many issued a month later). However I do have a UK copy in a phonogram company sleeve with typed promo leaflet (original not photocopy) and that has silver labels. I believe it possible that all silver label copies of D.I.Y. are promos although if anyone can confirm purchasing a stock copy at the time from a high street record store I am prepared to accept that as contrary evidence. (n.b.I once had Many too Many on both silver and purple labels and both were purchased new from record stores close to their release date). One other point of interest is the promo sheet with D.I.Y. states the release date of 12 May 1978, not 5 May claimed above.
