Thank youDave Scrimshaw helped me with my Holdsworth skip find. - he’s on this forum - look him up and ask him.
I got an idea of the model from pics on this site but members here confirmed it.
Dave Scrimshaw supplied some of his research into frame numbers and dates of manufacture in this thread on page 2
I would love it if it was a zephyr but all the pics show different lugs to mine, I don’t see any pics with the same lugs, I was told it would be around 1960 ?Looks like a Zephyr to me. All decals available from H Lloyd Cycles. 1961 or later as older ones had track ends. See https://www.nkilgariff.com/HoldsModelPages/Zephyr.htm
They came in any colour you fancied.
