Trying to find information and possible pricing on an R Fowler Marrickville teapot with number 36

[itssaturday]

Have a nice brown teapot with R Fowler Ltd Fitzroy St Marrickville and the number 36 stamped on the underside.   Wanting to tell it but need information and possible pricing.
Any help would be appreciated.  Have found other Australian pottery that looks similar.
