Trouble with a new 1927 12 Ga Trojan

[Scott Dupons]

I am new to this forum so please forgive me. I have just obtained a very nice Trojan 12. I believe that it may have been refinished or an attempt at restoration at one point due to its condition but that may or may not be correct. I have two issues with the gun that I could use some guidance with please. First the spring mechanism on the fore-end seems to be frozen. The roller is working but it is not receding when applied to the barrel. I assume at this point that a gunsmith is in order. Secondly, my barrels will not break from the receiver. They function properly. Cock and lock correctly and tight but when attempting to remove, they are loose but will not release. I have had dozens of side by sides and never encountered this. Does anyone have any suggestions? Thank you in advance for your patience with my ignorance.
