I recently inherited a model of the Rhoda Mary the hull has been completed to a good standard and the masts and bowsprite are in place.I have never built a model like this but would really like to complete it .However there are a few problems firstly there does not seem to be all the instructions there are two A1 sheets of drawings and photos and a typed 3 page building instruction though they are not to informative stating that words would only confuse when it came to assembling the rigging and the drawings are adequate. I think this is an old model as the plans are very tattered and yellowed ,Second the kit and tool box has stood for a long time and due to inquisitive children and relatives the bags containing many of the fittings have been pulled off the large numbered cards and have been lost or broken .Most have dropped to the bottom of the tool box and mixed with parts from other models.One major part that is missing is a brig sail spar from the misson  mast.Can the missing parts be replaced or is it possible to purchase the cards with the parts bagged and numbered.I would really like to complete this model and would greatly appreciate any advice,
