1950
Alan Colbeck, holder of the Lord Mountevans title in 1950, two years before the formation of Joint Promotions.
In an earlier discussion we find Colbeck stated as champion in January of 1950, but in The Mat of 12 months later, January, 1951, Johnny Stead is listed as lightweight champion and Colbeck as welterweight champion. The weight divisions are not the same as later adopted by Joint Promotions.
This looks to be a particularly good bill. I've seen Peter Preston versus Jon Cortez on a Morrell and Beresford bill at The King's Hall, Belle Vue with Cortez as blue eye and it was a good opening contest as I recall. At the same venue I've seen Maurice La Rue versus Tony St.Clair in a tag match (La Rue partnered by Haggetty and St.Clair partnered by Eagles; it went twenty minutes cats) but would have loved to have seen them in a singles affair. The other two bouts also look tasty.
