Martins right, the guide will be +40.
My advice would be to work with your club to come to a data based compromise that works for your boat. The class recommended numbers aren't especially scientific, and it's difficult to come up with a "one size fits all" solution for older boats with all the modifications available. Throw in the different water/wind characteristics of different clubs and you've no chance! Be realistic about your ability and the ability of the rest of the club fleet.
On a small lake in light winds you should find that you're at little disadvantage even with period rig off the standard PY. As the wind strength and the length of the offwind legs increases you will find yourself falling increasingly behind. Decent sails, preferably - but not essentially (You can make modern sails work quite well with minor set up adjustments, certainly better than 40 year old Banks') - cut for your rig will make a difference to your speed. You can't expect a handicap system to account for worn out sails.
