SAE to the museum :-

A £10 donation is now required for all dating either by cheque or PayPal.
Paper copies of any information held will be sent.
The museum has digitised all the remaining Petter drawings, a paper copy will be sent in a cardboard tube, one off cost £20 (cardboard tubes are getting pricey!), additional drawings £3 each. This is STILL a cheap service compared to other museums. Contact the museum first to find out if a drawing is held.
