Rovers Crest Reserch

I was asked by a friend to put out the following request to Rovers supporters. The present crest is not the origional we know but the question is how many different crests did Rovers have since 1928. I know of four; the present one, the one used during Willie McStay's reign, the original Sligo Crest (tree, shell and hare) and one with the letters SR from back in the forties I think.
Does anyone know where I'd get a copy of these crests on the internet.
This is for a project a young lad is doing on Rovers in college.

Here is the one we now now use
Rovers Crest after 1996

and the one from the one form the mid 1990's
Pre 1996 Crest

I'll see what I can do about the other ones :)

Here is the Rovers crest form the 1980s (black and white) I was looking at old program covers from the 60's and 70's we used the same crest back then expect it didn't say "Sligo Rovers FC" and "founded 1928" on it. I know the "SR" you are on about Petmuller we had it for the 1949 season
