Marlin 55

Looking to sell this odd ball model 55

I purchased it from a gun show as I had never seen one like it before. 

28 inch barrel with a 2 3/4  chamber

I don't know what choke is in it but I can get a measurement when I get a chance. 

I have never shot it personally but it functions flawless.

Some surface rust in last picture  by bolt handle 

Any information would be appreciated and I will update the add

A great piece for your collection 

Located in Tobermory Ontario 

would prefer local meet but can ship

Asking 550 obo
