Yes, get onto saving old seagulls. John has new and used parts for almost every model of seagull and can supply manuals for them as well. Also, try become a member of the SOS forum, where you can ask questions etc about your seagull.

There are two most common models, the 40 series and the 102 series. 40 series have a removable head with a square block and 102’s have a rounded block all cast into one.
The main problem with seagulls is that they corrode quite easily, so disassembling them can be quite a task if you don’t have heat.
Plug the engine no. of the seagull in here to find out what year, model etc it is.

Over here in Australia, seagulls are quite common.
Good luck with it.
