Parker or English?

[Big Friend Ten (BFT)]

My trusty EH has constrictions of .030" and .032". I've never patterened it to determine the actual choke. It seems to shoot tight enough using Nice Shot.

Most of the dozen or so Parker 10 gauges which I have measured have constrictions near .030". I think the tightest Parker 10 gauge constriction which I've measured is .035". I do however have a couple LC Smith 10's with .050" constrictions with unmolested bores of .775".

10 gauge guns on the three frame with 30 inch barrels generally weigh 9 to 9 1/4; there are some of that weight on two frames as well. You might find 9 1/2 with 32 inch barrels.
Orvis Manchester recently sold a 5 frame ten ; which was discussed here on the forum.
Going heavier than 9 1/4 in ten gauge probably requires a larger frame or longer barrels, which reduces the population available quite a bit.
I have a 9 pound 15 ounce 3 frame lifter, but it is a 32 inch 12 ga.

Best, Austin
