Well, mine (#1404 if we can take that as correct) has the motor well and does not have the traveller arrangement. So, sometime between 1961 (late) and 1963 (mid). Because "ctnidae" has the same hull configuration, the #1114 appears confirmed there.
You can read elsewhere on the site that sail numbers were not given out in strict sequence - one poster speculated they just had the sails made up in batches and would grab the nearest bag. Apparently there are some confirmed discrepancies between hull and sail # sequence.
Anyways, at a rate of 20-25 boats a month, #1114 would be 4-5 months younger than #1001. So it seems like the cutover didn't happen until at least '62. (If anyone has a boat in that range and can contribute details, that would be great!).
How are your jibsheets laid out originally?
My hull has two circular "platforms" about 4" across, molded into the side decks a little rear of the cuddy. These could have been used to mount jib-leads or blocks, from were the jib sheets would have been lead inboards trough the coamings. That was never done on my boat (the coamings don't have holes). More intriguing is the fact that there are holes for jib-leads that were drilled through the deck (but later filled with gel-coat in the factory - using the original color). The filled holes can easily be seen from underneath.
If I had to speculate, then either what was delivered with my boat was an option or they decided to change the setup, but had some decks built already - in either case, they must have decided to refurbish an existing deck.
