Yours looks OK Ian. Ist Jan and Oct 2025 were Wednesdays. I'm tempted to touch-drill the rear of the central rivet of mine to see if the under plate is in fact two bits, an inner and an outer. Then I might be able to move one round a touch. The alternative is to leave it as it is. If it's like postage stamps, an imperfect one is often worth ten times as much as a good one. DaveP
